Vito 2964a3b632 feat(thumbnails): WebP/JPEG XL thumbnails, server-side thumbnail settings and Convert outdated (#319)
* feat(thumbnails): thumbnail format, quality and size as server settings

Thumbnail format (webp default, jxl, jpeg), quality (1-100, default 80)
and size limit (128-2048 px, default 512) are server settings in the
config.json thumbnails section, saved with the settings revision. The
never-read gallery thumbnail_size is gone: older saves wrote its unused
default 256 into config.json.

One module names previews (<stem>_thumb.webp/.jxl/.jpg) and finds the
preview a source owns, preferring the configured format; legacy names
are still found. The encoder module writes every preview atomically and
verifies it decodes. JPEG XL needs no new dependency: Pillow (natively
or with pillow_jxl), ffmpeg with libjxl, or cjxl; without one the
settings refuse jxl (400 jxl-unavailable) and GET says why. Encoder
processes are tracked, bounded and killed at shutdown.

* feat(thumbnails): every preview writer and lookup follows the thumbnail settings

Automatic previews (capture and first view), the thumbnail job, the
legacy gallery routes and the history route write <stem>_thumb.webp
(or .jxl/.jpg) with the configured quality and size limit, for images
and videos alike: video frames, ffmpeg's included (a PNG on stdout,
never upscaled), and the placeholder are encoded like images.

Listings, duplicates, enrichment, the autotag scan and the history
route show any preview the file owns, the current format first, so
older _thumb.png previews keep working until converted. A request for
an older name answers the current preview. Previews are served with
an explicit image/webp or image/jxl type and the same cache headers.

The plan and status count missing, outdated (another format) and
ready previews; the missing job never writes beside an outdated one.
Removing a file removes its previews in every format; the clear
removes .webp and .jxl too. Encoder processes are killed at shutdown.

A preview is only a placeholder: inspection refuses paths under
thumbnails/ and always reads the original, and the inspector cover
accepts the listing's preview in any format the file owns.

* feat(thumbnails): Convert outdated thumbnails as an Activity job

POST /jobs/thumbnails {mode: "convert"} starts "Convert outdated
thumbnails" under the thumbnail job's kind, guarded admission, worker
threads and cancel at a file boundary. For each file whose preview is
in another format, it writes the new preview from the source (atomic,
verified; a video with no decodable frame fails instead of getting the
placeholder), then removes that file's old-format previews in its
thumbnails folder. A failure keeps the old preview; orphan previews
and links are never touched. The final line reports converted, failed
and bytes before and after. The plan counts it with mode=convert; the
legacy gallery stream refuses to attach to a running conversion.

* feat(thumbnails): thumbnail settings in Appearance and Convert outdated in the workspace

System > Appearance gains a Thumbnails surface: format (WebP, JPEG XL,
JPEG), quality and size limit, saved to the server with the settings
revision. JPEG XL is offered only when the server has an encoder, else
the option is disabled with the server's reason (D130); a note says
when this browser cannot show JPEG XL. Saving a new format converts
nothing: the row then says previews keep their old format.

Thumbnail maintenance gains the Convert outdated scope and names the
server's settings instead of its own quality and size fields (D131).
Overview's thumbnail row reads N missing, M outdated, K failed and
offers Convert outdated while previews are outdated.

The workspace decodes a tiny JPEG XL once: where it cannot, cards, the
Library and the inspector cover load the original for a .jxl preview,
and any preview that fails to load falls back to the original. The
viewer and downloads keep using the original (regression test).
README explains enabling JPEG XL; TESTING.md records D130 and D131.

* test(thumbnails): coverage floors for the thumbnail modules and WebP in page workflows

The two new frontend modules enter the coverage baseline (98% lines);
other floors only rise. The visual fixture's preview is WebP and
Appearance has its Thumbnails surface in the System shell check.

* fix(thumbnails): say when the thumbnail settings could not be read

Like Appearance's other server rows, the Thumbnails rows show 'Server
settings could not be read.' while the read failed, instead of only
staying disabled. Firefox exposed the gap: its JPEG XL note arrived
first and changed the row notes the page workflow counted.

* test(thumbnails): accept the legacy preview's spelling a case-insensitive disk finds

On Windows and macOS the '.jpg' lookup finds an older release's
b_thumb.JPG first, so the listed URL spells '.jpg'; it names the same
file there. The test now accepts either spelling and checks the URL
serves that preview.

* fix(thumbnails): address the final review of the thumbnail format work

- ffmpeg writes JPEG XL with -update 1, so a % in a file name is never an
  image-sequence pattern, and reads videos as file:<path>. The clear and a
  startup sweep remove temp files that interrupted writes left behind.
- Convert outdated converts each group of same-stem files once, from the
  first source in the R2 order. An old preview that is already gone counts
  as removed, and each file's bytes count once. A current preview is only
  kept if it decodes.
- An encoder that fails makes the write detect encoders again once. Another
  encoder is used if one is found; with none, the file is written as WebP
  and the availability Appearance shows is refreshed.
- Changing the thumbnail format, quality or size while Convert outdated runs
  returns 409 busy. If the format still changes underneath, the job stops
  without removing anything.
- Legacy preview spellings are matched case-insensitively, so X_thumb.JPG
  counts as outdated.
- History's cover uses the same lookup as Images. It serves .jxl only when
  Accept lists image/jxl, and otherwise the original or the placeholder.
- A video whose thumbnail the browser cannot show keeps its own element
  (Images) or its label (Library).

* fix(thumbnails): keep the new preview, probe encoders only when gone, sweep reused PIDs

- Convert never removes a path that is the preview it just wrote. It
  compares the device and inode, or the resolved and normcased paths when
  the disk has no inode numbers. This covers x_thumb.JPG on a
  case-insensitive disk.
- A JPEG XL encode failure re-runs encoder detection only when the
  encoder's binary or module is gone. A "no encoder" result is checked
  again on the settings read, on a jxl save, and after 60 s, so one slow
  probe no longer turns JPEG XL off until a restart.
- The startup sweep now also removes temp files that carry this process's
  PID but predate its start. Containers reuse PIDs.

* fix(history): let the cover ask for JPEG XL when this browser decodes it

Firefox can decode JPEG XL without listing image/jxl in Accept. When the
workspace's probe decodes JPEG XL, it adds jxl=1 to the History cover URL.
The server serves a .jxl preview when that flag is set or when Accept
lists image/jxl. In every other case it falls back as before. The flag
accepts only 0 or 1, and the response stays no-store.

* fix(thumbnails): keep going past the per-batch cap until every preview is made

The missing, rebuild and Convert outdated jobs stopped after
MAX_THUMBNAIL_FILES (10,000) files and said "N more on the next run", but
nothing ever started that next run. The cap now bounds one batch. After
each batch the job plans again, leaving out every file it already worked
on, and continues until nothing is left, the job is cancelled, or a batch
makes no progress. That last case stops on files that fail every time
instead of looping over them.

Activity progress counts against the overall total, and the final line and
the legacy stream's complete frame report every batch. Admission, worker
threads, cancellation and the #316 rules are unchanged. The Thumbnail
maintenance dialog now counts all the work instead of saying "more on the
next run".
