fix(backend): restore distinct copilot fallback model

### Why / What / How

**Why:** CoPilot's Graphiti memory system needed structured metadata to
distinguish memory types (rules, procedures, facts, preferences),
support scoped retrieval, enable targeted deletion, and track memory
costs under the AutoPilot billing account separately from the platform.

**What:** Adds the MemoryEnvelope metadata model, structured
rule/procedure memory types, a derived-finding lane for
assistant-distilled knowledge, two-step forget tools, scope-aware
retrieval filtering, AutoPilot-dedicated API key routing, and several
reliability fixes (streaming socket leaks, event-loop-scoped caches,
ingestion hardening).

**How:** MemoryEnvelope wraps every stored episode with typed metadata
(source_kind, memory_kind, scope, status, confidence) serialized as
JSON. Retrieval filters by scope at the context layer. The forget flow
uses a search-then-confirm two-step pattern. Ingestion queues and client
caches are scoped per event loop via WeakKeyDictionary to prevent
cross-loop RuntimeErrors in multi-worker deployments. API key resolution
falls back to AutoPilot-dedicated keys (CHAT_API_KEY,
CHAT_OPENAI_API_KEY) before platform-wide keys.

### Changes 🏗️

**New: MemoryEnvelope metadata model** (`memory_model.py`)
- Typed memory categories: fact, preference, rule, finding, plan, event,
procedure
- Source tracking: user_asserted, assistant_derived, tool_observed
- Scope namespacing: `real:global`, `project:<name>`, `book:<title>`,
`session:<id>`
- Status lifecycle: active, tentative, superseded, contradicted
- Structured `RuleMemory` and `ProcedureMemory` models for complex
instructions

**New: Targeted forget tools** (`graphiti_forget.py`)
- `memory_forget_search`: returns candidate facts with UUIDs for user
confirmation
- `memory_forget_confirm`: deletes specific edges by UUID after
confirmation

**New: Architecture test** (`architecture_test.py`)
- Validates no new `@cached(...)` usage around event-loop-bound async
clients
- Allowlists pre-existing violations for future cleanup

**Enhanced: memory_store tool** (`graphiti_store.py`)
- Accepts MemoryEnvelope metadata fields (source_kind, scope,
memory_kind, rule, procedure)
- Wraps content in MemoryEnvelope before ingestion

**Enhanced: memory_search tool** (`graphiti_search.py`)
- Scope-aware retrieval with hard filtering on group_id

**Enhanced: Ingestion pipeline** (`ingest.py`)
- Derived-finding lane: distills substantive assistant responses into
tentative findings
- Event-loop-scoped queues and workers via WeakKeyDictionary (fixes
multi-worker RuntimeError)
- Improved error handling and dropped-episode reporting

**Enhanced: Client cache** (`client.py`)
- Per-loop client cache and lock via WeakKeyDictionary (fixes "Future
attached to a different loop")

**Enhanced: Warm context** (`context.py`)
- Filters out non-global-scope episodes from warm context

**Fix: Streaming socket leak** (`baseline/service.py`)
- try/finally around async stream iteration to release httpx connections
on early exit

**Config: AutoPilot key routing** (`config.py`, `.env.default`)
- LLM key fallback: GRAPHITI_LLM_API_KEY → CHAT_API_KEY →
OPEN_ROUTER_API_KEY
- Embedder key fallback: GRAPHITI_EMBEDDER_API_KEY → CHAT_OPENAI_API_KEY
→ OPENAI_API_KEY
- Backwards-compatible: existing behavior unchanged until new keys are
provisioned

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
- [x] `poetry run pytest backend/copilot/graphiti/config_test.py` — 16
tests pass (key fallback priority)
- [x] `poetry run pytest backend/copilot/tools/graphiti_store_test.py` —
store envelope tests pass
- [x] `poetry run pytest backend/copilot/graphiti/ingest_test.py` —
ingestion tests pass

#### For configuration changes:
- [x] `.env.default` is updated or already compatible with my changes
- [x] `docker-compose.yml` is updated or already compatible with my
changes
- Configuration changes:
- New optional env var `CHAT_OPENAI_API_KEY` — AutoPilot-dedicated
OpenAI key for Graphiti embeddings (falls back to `OPENAI_API_KEY` if
not set)
- `CHAT_API_KEY` now used as first fallback for Graphiti LLM calls (was
`OPEN_ROUTER_API_KEY`)
- Infra action needed: add `CHAT_OPENAI_API_KEY` sealed secret in
`autogpt-shared-config` values (dev + prod)

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Touches Graphiti memory ingestion/retrieval and introduces hard-delete
capabilities plus event-loop–scoped caching/queues; failures could
affect memory correctness or delete the wrong edges. Also changes
streaming resource cleanup and key routing, which could surface as
connection or billing/cost attribution issues if misconfigured.
> 
> **Overview**
> **Graphiti memory is upgraded from plain text episodes to a structured
JSON `MemoryEnvelope`.** `memory_store` now wraps content with typed
metadata (source, kind, scope, status) and optional structured
`rule`/`procedure` payloads, and ingestion supports JSON episodes.
> 
> **Memory retrieval and lifecycle controls are expanded.**
`memory_search` adds optional scope hard-filtering to prevent
cross-scope leakage, warm-context formatting drops non-global scoped
episodes (and avoids empty wrappers), and new two-step tools
(`memory_forget_search` → `memory_forget_confirm`) enable targeted soft-
or hard-deletion of specific graph edges by UUID.
> 
> **Reliability and multi-worker safety improvements.** Graphiti client
caching and ingestion worker registries are now per-event-loop (avoiding
cross-loop `Future` errors), streaming chat completions explicitly close
async streams to prevent `CLOSE_WAIT` socket leaks, warm-context is
injected into the first user message to keep the system prompt
cacheable, and a new `architecture_test.py` blocks future process-wide
caching of event-loop–bound async clients. Config updates route Graphiti
LLM/embedder keys to AutoPilot-specific env vars first, and OpenAPI
schema exports include the new memory response types.

+"""Tests for transcript context coverage when switching between fast and SDK modes.
+
+When a user switches modes mid-session the transcript must bridge the gap so
+neither the baseline nor the SDK service loses context from turns produced by
+the other mode.
+
+Cross-mode transcript flow
+==========================
+
+Both ``baseline/service.py`` (fast mode) and ``sdk/service.py`` (extended_thinking
+mode) read and write the same JSONL transcript store via
+``backend.copilot.transcript.upload_transcript`` /
+``download_transcript``.
+
+Fast → SDK switch
+-----------------
+On the first SDK turn after N baseline turns:
+  • ``use_resume=False``  — no CLI session exists from baseline mode.
+  • ``transcript_msg_count > 0`` — the baseline transcript is downloaded and
+    validated successfully.
+  • ``_build_query_message`` must inject the FULL prior session (not just a
+    "gap" since the transcript end) because the CLI has zero context without
+    ``--resume``.
+  • After our fix, ``session_id`` IS set, so the CLI writes a session file
+    on this turn → ``--resume`` works on T2+.
+
+SDK → Fast switch
+-----------------
+On the first baseline turn after N SDK turns:
+  • The baseline service downloads the SDK-written transcript.
+  • ``_load_prior_transcript`` loads and validates it normally — the JSONL
+    format is identical regardless of which mode wrote it.
+  • ``transcript_covers_prefix=True`` → baseline sends ONLY new messages in
+    its LLM payload (no double-counting of SDK history).
+
+Scenario table (SDK _build_query_message)
+==========================================
+
+| # | Scenario                       | use_resume | tmc | Expected query message          |
+|---|--------------------------------|------------|-----|---------------------------------|

+"""Tests for the pre-create assistant message logic that prevents

+
+Reproduces the bug where:
+  1. Tool result is saved by intermediate flush → last_role=tool
+  2. SDK generates a text response
+  3. GeneratorExit at StreamStartStep yield (client disconnect)
+  4. _dispatch_response(StreamTextDelta) is never called
+  5. Session saved with last_role=tool instead of last_role=assistant
+
+The fix: before yielding any events, pre-create the assistant message in
+ctx.session.messages when has_tool_results=True and a StreamTextDelta is
+present in adapter_responses.  This test verifies the resulting accumulator
+state allows correct content accumulation by _dispatch_response.

+
+    Scope / limitations (best-effort optimisation, not a correctness primitive):
+    - Pod-local: ``_listener_sessions`` is in-memory. If the DELETE request
+      lands on a different worker than the one serving the SSE, no listener
+      is cancelled here — the SSE worker still releases on its XREAD timeout.
+    - Session-scoped (not subscriber-scoped): cancels every active listener
+      for the session on this pod. In the rare case a single user opens two
+      SSE connections to the same session on the same pod (e.g. two tabs),
+      both would be torn down. Cross-pod, subscriber-scoped cancellation
+      would require a Redis pub/sub fan-out with per-listener tokens; that
+      is not implemented here because the XREAD timeout already bounds the
+      worst case.
+
+    Returns the number of listener tasks that were cancelled.

+# AsyncRabbitMQ, supabase AClient, ...) wrap connection pools whose internal
+# asyncio primitives lazily bind to the first event loop that uses them. The
+# executor runs two long-lived loops on separate threads; once the cache is
+# populated from loop A, any subsequent call from loop B raises
+# `RuntimeError: ... bound to a different event loop`, surfaced as an opaque
+# `APIConnectionError: Connection error.` and poisons the cache for a full
+# TTL window.
+#
