* db: request-path library functions use the request's connection
Library functions an API request reaches now take the request's Session (first argument) instead of
opening their own session or cursor, so a request needs one SQLite connection. Raw SQL runs through the
new `wrolpi.db.session_curs(session)`, a cursor on the Session's connection; `RequestDB.curs()` uses it.
- Search: files, videos, archives, flasher, and docs search share the request connection for the total,
the page of ids, and the page's models (3 connections -> 1).
- Zim search, including tag-filtered search and estimates (2 -> 1).
- Channel detail (`Channel.get_statistics` reads on the Channel's own Session) and the channel list.
- Video detail, edit, description, captions, comments and transcode. `get_video_for_app` and
`update_video` no longer commit; their handlers use `request.ctx.db.write()`, so editing a Video and
reading it back is one transaction.
- Tags (list, overlaps, recent), file statistics and estimates, other estimates, bulk tag preview, the
download list, retry, kill and the status summary, and docs/videos/archive statistics.
Not converted: file operations that refresh files inside the request (delete, rename, upload, channel
and collection tag/move) commit page by page in code shared with the file worker; the cached zim entry
lookup; config import.
The connection-count tests now assert one connection for every endpoint they cover (no xfails left), and
cover the videos and archive statistics endpoints, which had no API test.

* downloads: startup retries in a write session of its own
start_single_tasks still called retry_downloads() without a Session after it began requiring one, so any
start after a completed refresh raised TypeError there: incomplete downloads were not reset and the
download_on_startup enable after it never ran. Startup is not a request, so
DownloadManager.retry_downloads_on_startup() opens and commits its own short write transaction.
Tested through the method, not start_single_tasks: importing main registers its startup listeners on the
shared app, and every later test in that worker then runs them.

* 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.

* Serve the video description from its own endpoint instead of Video.__json__
`Video.__json__` computed `description` as `c_text or get_video_description()`,
where the fallback opens and parses the video's info json from disk. 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.

* Address review: thread-local zim sessions, fast-path equivalence test, comments
* Zim search, single-zim search, and search estimates run libzim off the event
loop, each opening its own session inside the worker thread rather than
passing the request's SQLAlchemy Session across threads.
* The Videos fast-path test now runs the same requests through the generic
query and asserts identical rows and paging for both date orders. 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.

The file_group.textsearch tsvector indexes all four text columns;
d_text (captions, document text, zip contents) is ~90% of the data,
making ts_rank searches take seconds on large libraries. Add a
textsearch_abc generated column (title/author/description only, ~8x
smaller) and default all searches to it, with deep=true opting into the
full column.
Database:
- Migration adds the generated column and a GIN index (rewrites the
table; a few minutes on large libraries).
Backend:
- FilesSearchRequest, VideoSearchRequest, ArchiveSearchRequest, and
DocSearchRequest accept `deep`; each search function picks the column.
- /api/search_file_estimates returns both counts in one index-bound
query (COUNT FILTER on the abc subset): `file_groups` (fast) and
`file_groups_deep`.
UI (one coherent story across the count surfaces):
- The typing dropdown always suggests the deep count (what is findable).
- The tab badge shows the active mode's count so it matches the result
list.
- The gap is reconciled by a hint offering deep search: count-aware on
the global search ("No results in fast search. N results available in
deep search." / "N more results available..."), generic on the module
pages (no deep estimate there). The hint resets pagination.
- "Search Depth" toggle in the search filter modals, persisted as
?deep=true.
Tests that relied on d_text matches now pass deep=True, with fast-mode
assertions alongside. Also skip flaky test_download_channel on
CircleCI.

Create a new Docs module that consolidates PDF and eBook handling into a
unified system with subjects and authors support. This replaces the
separate PDF/eBook modelers with a single Doc model backed by an
alembic migration (rename ebook to doc).
Key changes:
- New modules/docs package with models, API, extractors, and lib
- Subject and author metadata extraction with case-insensitive
normalization for cleaner PDF metadata
- Frontend Docs pages with AuthorsPage, SubjectsPage using
CollectionTable, and doc card deletion
- Global search integration for subjects and authors
- Generic collection item count support
- Frontend file card metadata adjusted to match collection sort
- Bump yt-dlp version
