Merge branch 'dev' into fix/classic-docs-cleanup

### Why / What / How

**Why:** The share page was unbranded (no logo/navigation) and images
from workspace files couldn't render because the proxy didn't handle
public share URLs. Zip downloads also had several gaps — no size limits,
no workspace file support, silent failures on data URLs, and single
files got wrapped in unnecessary zips.

**What:** Adds AutoGPT branding to the share page, secure public access
to workspace files via a SharedExecutionFile allowlist, and a hardened
zip download module.

**How:** Backend scans execution outputs for `workspace://` URIs on
share-enable and persists an allowlist in a new `SharedExecutionFile`
table. A new unauthenticated endpoint serves files validated against
this allowlist. Frontend proxy routing is extended (with UUID
validation) to handle the 7-segment public share download path as a
binary response. Download logic is consolidated into a shared module
with size limits, parallel fetches, filename sanitization, and
single-file direct download.

### Changes 🏗️

**Share page branding:**
- AutoGPT logo header centered at top, linking to `/`
- Dark/light mode variants with correct `priority` on visible variant
only

**Secure public workspace file access (backend):**
- New `SharedExecutionFile` Prisma model with `@@unique([shareToken,
fileId])` constraint
- `_extract_workspace_file_ids()` scans outputs for `workspace://` URIs
(handles nested dicts/lists)
- `create_shared_execution_files()` / `delete_shared_execution_files()`
manage allowlist lifecycle
- Re-share cleans up stale records before creating new ones (prevents
old token access)
- `GET /public/shared/{token}/files/{id}/download` — validates against
allowlist, uniform 404 for all failures
- `Content-Disposition: inline` for share page rendering
- Hand-written Prisma migration
(`20260417000000_add_shared_execution_file`)

**Frontend proxy fix:**
- `isWorkspaceDownloadRequest` extended to match public share path
(7-segment)
- UUID format validation on dynamic path segments (file IDs, share
tokens)
- 30+ adversarial security tests: path traversal, SQL injection, SSRF
payloads, unicode homoglyphs, null bytes, prototype pollution, etc.

**Download module (`download-outputs.ts`):**
- Consolidated from two divergent copies into single shared module
- `fetchFileAsBlob` with content-length pre-check before buffering
- `sanitizeFilename` strips path traversal, leading dots, falls back to
"file"
- `getUniqueFilename` deduplicates with counter suffix
- `fetchInParallel` with configurable concurrency (5)
- 50 MB per-file limit, 200 MB aggregate limit
- Data URL try-catch, relative URL support (`/api/proxy/...`)
- Single-file downloads skip zip, go directly to browser download
- Dynamic JSZip import for bundle optimization
- 26 unit tests

**Share page file rendering:**
- `WorkspaceFileRenderer` builds public share URLs when `shareToken` is
in metadata
- `RunOutputs` propagates `shareToken` to renderer metadata

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Adds a new unauthenticated file download path gated by a database
allowlist plus a new Prisma model/migration; mistakes here could expose
workspace files or break sharing. Frontend download behavior also
changes significantly (zipping/fetching), which could impact
large-output performance and edge cases.
> 
> **Overview**
> Enables **public rendering and downloading of workspace files on
shared execution pages** by introducing a `SharedExecutionFile`
allowlist tied to the share token and populating it when sharing is
enabled (and clearing it on disable/re-share).
> 
> Adds `GET /public/shared/{share_token}/files/{file_id}/download` (no
auth) that validates the requested file against the allowlist and
returns a uniform 404 on failure; workspace download responses now
support `inline` `Content-Disposition` via the exported
`create_file_download_response` helper.
> 
> Frontend updates the share page to pass `shareToken` into output
renderers so `WorkspaceFileRenderer` can build public-share download
URLs; the proxy matcher is extended/strictly UUID-validated for both
workspace and public-share download paths with extensive adversarial
tests. Output downloading is consolidated into `download-outputs.ts`
using dynamic `jszip` import, filename sanitization/deduping,
concurrency + size limits, and a single-file non-zip fast path.

 **Prevention:** Add `sleep 3` between individual thread reply API calls. When posting >20 replies, increase to `sleep 5`.
 
-**Recovery from secondary rate limit (403):**
+### Detection
+
+The `gh` CLI surfaces the GraphQL limit on stderr with the exact string `GraphQL: API rate limit already exceeded for user ID <id>` and exits 1 — any `gh api graphql ...` **or** `gh pr view ...` call fails. Check current quota and reset time via the REST endpoint that reports GraphQL quota (this call is REST and still works whether GraphQL is rate-limited OR fully down):
+
+```bash
+gh api rate_limit --jq '.resources.graphql'   # { "limit": 5000, "used": 5000, "remaining": 0, "reset": 1729...}
+# Human-readable reset:
+gh api rate_limit --jq '.resources.graphql.reset' | xargs -I{} date -r {}
+```
+
+Retry when `remaining > 0`. If you need to proceed sooner, sleep 2–5 min and probe again — the limit is per user, not per machine, so other concurrent agents under the same token also consume it.
+
+### What keeps working
+
+When GraphQL is unavailable (rate-limited or outage):
+
+- **Keeps working (REST):** top-level reviews fetch, conversation comments fetch, all inline-comment replies, CI status (`gh pr checks`), and the `gh api rate_limit` probe.
+- **Degraded:** inline thread list — fall back to flat `/pulls/{N}/comments` REST, which drops thread grouping, `isResolved`, and Relay thread IDs. You still get comment bodies and the `databaseId` as `id`, enough to read and reply.
+- **Blocked:** `gh pr view`, the `resolveReviewThread` mutation, and any new `gh api graphql` queries — wait for the quota to reset.
+
+### Fall back to REST
+
+**PR metadata reads** — `gh pr view` uses GraphQL under the hood; use the REST pulls endpoint instead, which returns the full PR object:
+
+```bash
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N} --jq '.body'           # == --json body
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N} --jq '.base.ref'       # == --json baseRefName
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N} --jq '.mergeable'      # == --json mergeable
+```
+
+Note: REST `mergeable` returns `true|false|null`; GraphQL returns `MERGEABLE|CONFLICTING|UNKNOWN`. The `null` case maps to `UNKNOWN` — treat it the same (still computing; poll again).
+
+**Inline comments (flat list)** — no thread grouping or `isResolved`, but enough to read and reply:
+
+```bash
+gh api repos/Significant-Gravitas/AutoGPT/pulls/{N}/comments --paginate \
+  | jq '[.[] | {id, path, line, user: .user.login, body: .body[:200], in_reply_to_id}]'
+```
+
+Use this degraded mode to make progress on the fix → reply loop, then return to GraphQL for `resolveReviewThread` once the rate limit resets.
+
+**Replies** — already REST-native (`/pulls/{N}/comments/{ID}/replies`); no change needed, use the same command as the main flow.
+
+**`resolveReviewThread`** — **no REST equivalent**; GitHub does not expose a REST endpoint for thread resolution. Queue the thread IDs needing resolution, wait for the GraphQL limit to reset, then run the resolve mutations in a batch (with `sleep 3` between calls, per the secondary-limit guidance).

+Multiple worktrees share the same host — Docker infra (postgres, redis, clamav), app ports (3000/8006/…), and the test user. Two agents running `/pr-test` concurrently will corrupt each other's state (connection-pool exhaustion, port binds failing silently, cross-test assertions).

+
+### 3e-native. Run the app natively (PREFERRED for iterative dev)
+
+Native mode runs infra (postgres, supabase, redis, rabbitmq, clamav) in docker but runs the backend and frontend directly on the host. This avoids the 3-8 minute `docker compose build` cycle on every backend change — code edits are picked up on process restart (seconds) instead of a full image rebuild.
+
+**When to prefer native mode (default for this skill):**
+- Iterative dev/debug loops where you're editing backend or frontend code between test runs
+- Any PR that touches Python/TS source but not Dockerfiles, compose config, or infra images
+- Fast repro of a failing scenario — restart `poetry run app` in a couple of seconds
+
+**When to prefer docker mode (3e fallback):**
+- Testing changes to `Dockerfile`, `docker-compose.yml`, or base images
+- Production-parity smoke tests (exact container env, networking, volumes)
+- CI-equivalent runs where you need the exact image that'll ship
+
+**Note on 3b (copilot auth):** no npm install anywhere. `poetry install` pulls in `claude_agent_sdk`, which ships its own Claude CLI binary — available on `PATH` whenever you run commands via `poetry run` (native) OR whenever the copilot_executor container is built from its Poetry lockfile (docker). The OAuth token extraction still applies (same `refresh_claude_token.sh` call).
+
+**Preamble:** before starting native, run the kill-stray + free-ports block from 3c's "Native mode also" subsection.
+
+**1. Start infra only (one-time per session):**
+
+```bash
+cd $PLATFORM_DIR && docker compose --profile local up deps --detach --remove-orphans --build
+```
+
+This brings up postgres/supabase/redis/rabbitmq/clamav and skips all app services.
+
+**2. Start the backend natively:**
+
+```bash
+cd $BACKEND_DIR && (poetry run app 2>&1 | tee .ign.application.logs) &
+```
+
+`poetry run app` spawns **all** app subprocesses — `rest_server`, `executor`, `copilot_executor`, `websocket`, `scheduler`, `notification_server`, `database_manager` — inside ONE parent process. No separate containers, no separate terminals. The `.ign.application.logs` prefix is already gitignored.
+
+**3. Wait for the backend on :8006 BEFORE starting the frontend.** This ordering matters — the frontend's `pnpm dev` startup invokes `generate-api-queries`, which fetches `/openapi.json` from the backend. If the backend isn't listening yet, `pnpm dev` fails immediately.
+
+```bash
+for i in $(seq 1 60); do
+  if [ "$(curl -s -o /dev/null -w '%{http_code}' http://localhost:8006/docs 2>/dev/null)" = "200" ]; then
+    echo "Backend ready"
+    break
+  fi
+  sleep 2
+done
+```
+
+**4. Start the frontend natively:**
+
+```bash
+cd $FRONTEND_DIR && (pnpm dev 2>&1 | tee .ign.frontend.logs) &
+```
+
+**5. Wait for the frontend on :3000:**
+
+```bash
+for i in $(seq 1 60); do
+  if [ "$(curl -s -o /dev/null -w '%{http_code}' http://localhost:3000 2>/dev/null)" = "200" ]; then
+    echo "Frontend ready"
+    break
+  fi
+  sleep 2

+**Symptom:** Copilot logs say `claude: command not found` or similar when starting an SDK turn.

+**Fix:** Rebuild the image cleanly: `docker compose build --no-cache copilot_executor && docker compose up -d copilot_executor`. Do NOT `docker exec ... npm install -g @anthropic-ai/claude-code` — that is outdated guidance and will pollute the container with a second CLI that the SDK won't use.

-### 🎯 Benchmark
+### 🎯 Direct Benchmark
 
-**Measure your agent's performance!** The `agbenchmark` can be used with any agent that supports the agent protocol, and the integration with the project's [CLI] makes it even easier to use with AutoGPT and forge-based agents. The benchmark offers a stringent testing environment. Our framework allows for autonomous, objective performance evaluations, ensuring your agents are primed for real-world action.
+**Measure your agent's performance!** The `direct_benchmark` harness tests agents directly without the agent protocol overhead. It supports multiple prompt strategies (one_shot, reflexion, plan_execute, tree_of_thoughts, etc.) and model configurations, with parallel execution and detailed reporting.

-### 💻 UI
-
-**Makes agents easy to use!** The `frontend` gives you a user-friendly interface to control and monitor your agents. It connects to agents through the [agent protocol](#-agent-protocol), ensuring compatibility with many agents from both inside and outside of our ecosystem.

-<!-- TODO: insert screenshot of front end -->
-
-The frontend works out-of-the-box with all agents in the repo. Just use the [CLI] to run your agent of choice!

 ### ⌨️ CLI
 
 [CLI]: #-cli
 
-To make it as easy as possible to use all of the tools offered by the repository, a CLI is included at the root of the repo:
+AutoGPT Classic is run via Poetry from the `classic/` directory:
 
 ```shell
-$ ./run
-Usage: cli.py [OPTIONS] COMMAND [ARGS]...
-
-Options:
-  --help  Show this message and exit.
-
-Commands:
-  agent      Commands to create, start and stop agents
-  benchmark  Commands to start the benchmark and list tests and categories
-  setup      Installs dependencies needed for your system.
+cd classic
+poetry install
+poetry run autogpt        # Interactive CLI mode
+poetry run serve --debug  # Agent Protocol server
 ```
 
-Just clone the repo, install dependencies with `./run setup`, and you should be good to go!
+See the [classic README](https://github.com/Significant-Gravitas/AutoGPT/tree/master/classic) for full setup instructions.

+"""Pending-message buffer for in-flight copilot turns.
+
+When a user sends a new message while a copilot turn is already executing,
+instead of blocking the frontend (or queueing a brand-new turn after the
+current one finishes), we want the new message to be *injected into the
+running turn* — appended between tool-call rounds so the model sees it
+before its next LLM call.
+
+This module provides the cross-process buffer that makes that possible:
+
+- **Producer** (chat API route): pushes a pending message to Redis and
+  publishes a notification on a pub/sub channel.
+- **Consumer** (executor running the turn): on each tool-call round,
+  drains the buffer and appends the pending messages to the conversation.
+
+The Redis list is the durable store; the pub/sub channel is a fast
+wake-up hint for long-idle consumers (not used by default, but available
+for future blocking-wait semantics).
+
+A hard cap of ``MAX_PENDING_MESSAGES`` per session prevents abuse.  The
+buffer is trimmed to the latest ``MAX_PENDING_MESSAGES`` on every push.

+``user_id`` against the authenticated caller.

+  until ``StreamFinish`` / ``StreamError`` (terminal) or the per-call
+  cap fires. On terminal, the aggregated :class:`SessionResult` comes
+  back in memory — no DB round-trip for the response content.
+* **Just check** — ``wait_if_running=0`` skips the subscription. If the
+  sub's last assistant message already looks terminal, returns
+  ``completed`` with that content.
+* **Cancel** — fan out a ``CancelCoPilotEvent`` on the shared cancel
+  exchange. Whichever worker is running the sub breaks out of its
