Otto 15bcdae4e8 fix(backend/copilot): Clean up GCSWorkspaceStorage per worker (#12153)
The copilot executor runs each worker in its own thread with a dedicated
event loop (`asyncio.new_event_loop()`). `aiohttp.ClientSession` is
bound to the event loop where it was created — using it from a different
loop causes `asyncio.timeout()` to fail with:

```
RuntimeError: Timeout context manager should be used inside a task
```

This was the root cause of transcript upload failures tracked in
SECRT-2009 and [Sentry
#7272473694](https://significant-gravitas.sentry.io/issues/7272473694/).

### Fix

**One `GCSWorkspaceStorage` instance per event loop** instead of a
single shared global.

- `get_workspace_storage()` now returns a per-loop GCS instance (keyed
by `id(asyncio.get_running_loop())`). Local storage remains shared since
it has no async I/O.
- `shutdown_workspace_storage()` closes the instance for the **current**
loop only, so `session.close()` always runs on the loop that created the
session.
- `CoPilotProcessor.cleanup()` shuts down workspace storage on the
worker's own loop, then stops the loop.
- Manager cleanup submits `cleanup_worker` to each thread pool worker
before shutting down the executor — replacing the old approach of
creating a temporary event loop that couldn't close cross-loop sessions.

### Changes

| File | Change |
|------|--------|
| `util/workspace_storage.py` | `GCSWorkspaceStorage` back to simple
single-session class; `get_workspace_storage()` returns per-loop GCS
instance; `shutdown_workspace_storage()` scoped to current loop |
| `copilot/executor/processor.py` | Added `CoPilotProcessor.cleanup()`
and `cleanup_worker()` |
| `copilot/executor/manager.py` | Calls `cleanup_worker` on each thread
pool worker during shutdown |

Fixes SECRT-2009
