 		Restore task snapshot via a worker-level dependency (#3945) 
* Restore task snapshot via a worker-level dependency

`get_access_token()` returned `None` inside background tasks whenever
`FASTMCP_DOCKET_URL` pointed at a `redis+cluster://` URL. The write side
was fine — it went through `docket.redis()`, which is cluster-aware —
but fastmcp kept a parallel sync Redis client just to read the snapshot
back, and `Redis.from_url()` rejects the cluster scheme.

Docket 0.19.1 ships worker-level dependencies that resolve per task in
the same asyncio.Task as user code, so ContextVars propagate cleanly.
That lets us load the snapshot once via `restore_task_snapshot` and
drop the sync Redis path entirely. Sync helpers like
`get_access_token()` and `get_http_request()` now just read a
ContextVar; Docket is the sole Redis consumer.

Closes #3897

* Revert TaskKey stub to a plain return

NotImplementedError would fire at module import if anything evaluated
the default; a no-op stub keeps the module usable without the
fastmcp[tasks] extra, which is what we want.
