* Fix API stalls: non-blocking switch worker, threaded searches, indexed Videos page Three response-time fixes found by benchmarking the read-only API endpoints hot and cold on real libraries: * `switch_worker` runs on the Sanic worker's event loop every 0.1s and called the blocking `multiprocessing.Event.wait(timeout=1)`. With no switch pending (the normal state) this froze the loop for a second at a time; about a third of all requests, including trivial ones, took ~1,000 ms. It now polls `is_set()` and returns immediately. * The search handlers (videos, files, archives, docs, zims) and `/api/statistics` ran synchronous SQLite queries on the event loop, so one slow search stalled every other request on that worker. They now run via `asyncio.to_thread`. * The unfiltered Videos page (`POST /api/videos/search` with only an order) used `mimetype LIKE 'video/%' OR ...` plus `COUNT(*) OVER()`, which visits every video's index entry before LIMIT applies: seconds cold on a large library on a spinning disk, and ~10 s hot for a deep page. It now seeks each exact mimetype on the (mimetype, effective_datetime) index for `limit + offset` rows and merges them, with the total from a separate count cached for 60 s. Results are identical to the generic query. Also adds `scripts/api_perf.py` (times every read-only endpoint against a host, optionally restarting the API over SSH for cold numbers) and `scripts/api_perf_compare.py` (merges per-host results). Host profiles live in a gitignored JSON file; an example is included. Measured on an 8-core docker host with a 10 GB library: median hot request 1,007 ms -> 22 ms; Videos page 1 hot 287 -> 108 ms, page 50 1,345 -> 120 ms.

The list endpoints serialize every result with `__json__`, so any page containing videos without an indexed description (common: many videos have none) read their info json files on every request, cold, for a field the list never displays. The description is not part of search either: search runs against the FTS copy of `c_text`, so the fallback never fed the index. Drop `description` from `__json__` and serve it from `GET /api/videos/<id>/description`, like comments and captions. The endpoint returns the indexed `c_text`, falling back to the info json only there, for a row indexed before descriptions were stored. The player page fetches it through `useVideoExtras` alongside the comments. Tests assert the list and detail responses never touch the info json, and cover the endpoint's indexed, fallback, and not-found cases.

The one intentional difference is documented: past the end, the fast path still reports the true total. * switch_worker returns before its try block so the empty path does not clear the event; its comment states the invariant only. The copied "synchronous SQLite" comments are reduced to one line in one place.
