fix(backend/copilot): prevent double upload in timeout handling

Previous fix created NEW task after timeout, causing double upload:
- Original shielded task still running
- New task also uploading same transcript

Correct fix: Create task FIRST, then shield it. If timeout occurs,
track the SAME task (no double upload).

Fixes double-upload bug in b8c65e3d2

-"""Redis Streams consumer for operation completion messages.
-
-This module provides a consumer (ChatCompletionConsumer) that listens for
-completion notifications (OperationCompleteMessage) from external services
-(like Agent Generator) and triggers the appropriate stream registry and
-chat service updates via process_operation_success/process_operation_failure.
-
-Why Redis Streams instead of RabbitMQ?
---------------------------------------
-While the project typically uses RabbitMQ for async task queues (e.g., execution
-queue), Redis Streams was chosen for chat completion notifications because:
-
-1. **Unified Infrastructure**: The SSE reconnection feature already uses Redis
-   Streams (via stream_registry) for message persistence and replay. Using Redis
-   Streams for completion notifications keeps all chat streaming infrastructure
-   in one system, simplifying operations and reducing cross-system coordination.
-
-2. **Message Replay**: Redis Streams support XREAD with arbitrary message IDs,
-   allowing consumers to replay missed messages after reconnection. This aligns
-   with the SSE reconnection pattern where clients can resume from last_message_id.
-
-3. **Consumer Groups with XAUTOCLAIM**: Redis consumer groups provide automatic
-   load balancing across pods with explicit message claiming (XAUTOCLAIM) for
-   recovering from dead consumers - ideal for the completion callback pattern.
-
-4. **Lower Latency**: For real-time SSE updates, Redis (already in-memory for
-   stream_registry) provides lower latency than an additional RabbitMQ hop.
-
-5. **Atomicity with Task State**: Completion processing often needs to update
-   task metadata stored in Redis. Keeping both in Redis enables simpler
-   transactional semantics without distributed coordination.
-
-The consumer uses Redis Streams with consumer groups for reliable message
-processing across multiple platform pods, with XAUTOCLAIM for reclaiming
-stale pending messages from dead consumers.

+- Runs locally — no cloud account required
+- Full interaction support: click, fill, scroll, login flows, multi-step
+- Session persistence via --session-name: cookies/auth carry across tool calls
+  within the same Copilot session, enabling login → navigate → extract workflows
+- Screenshot with --annotate overlays @ref labels, saved to workspace for user
+- The Claude Agent SDK's multi-turn loop handles orchestration — each tool call
+  is one browser action; the LLM chains them naturally
+
+SSRF protection:
+  Uses the shared validate_url() from backend.util.request, which is the same
+  guard used by HTTP blocks and web_fetch. It resolves ALL DNS answers (not just
+  the first), blocks RFC 1918, loopback, link-local, 0.0.0.0/8, multicast,
+  and all relevant IPv6 ranges, and applies IDNA encoding to prevent Unicode
+  domain attacks.

-Full Bash scripting is allowed (loops, conditionals, pipes, functions, etc.).
-Safety comes from OS-level isolation (bubblewrap): only system dirs visible
-read-only, writable workspace only, clean env, no network.
+When an E2B sandbox is available in the current execution context the command
+runs directly on the remote E2B cloud environment.  This means:
 
-Requires bubblewrap (``bwrap``) — the tool is disabled when bwrap is not
-available (e.g. macOS development).
+- **Persistent filesystem**: files survive across turns via HTTP-based sync
+  with the sandbox's ``/home/user`` directory (E2B files API), shared with
+  SDK Read/Write/Edit tools.
+- **Full internet access**: E2B sandboxes have unrestricted outbound network.
+- **Execution isolation**: E2B provides a fresh, containerised Linux environment.
+
+When E2B is *not* configured the tool falls back to **bubblewrap** (bwrap):
+OS-level isolation with a whitelist-only filesystem, no network, and resource
+limits.  Requires bubblewrap to be installed (Linux only).

+"""E2B sandbox lifecycle for CoPilot: persistent cloud execution.
+
+Each session gets a long-lived E2B cloud sandbox.  ``bash_exec`` runs commands
+directly on the sandbox via ``sandbox.commands.run()``.  SDK file tools
+(read_file/write_file/edit_file/glob/grep) route to the sandbox's
+``/home/user`` directory via E2B's HTTP-based filesystem API — all tools
+share a single coherent filesystem with no local sync required.
+
+Lifecycle
+---------
+1. **Turn start** – connect to the existing sandbox (sandbox_id in Redis) or
+   create a new one via ``get_or_create_sandbox()``.
+2. **Execution** – ``bash_exec`` and MCP file tools operate directly on the
+   sandbox's ``/home/user`` filesystem.
+3. **Session expiry** – E2B sandbox is killed by its own timeout (session_ttl).
