* feat(playback): add IsPGS helper and sup streaming extract path
PGS (Blu-ray bitmap) subtitle tracks can be copied losslessly into a .sup
elementary stream for client-side rendering, so they no longer have to be
burned in. streamExtractOutput maps PGS to (copy, sup), and the seek/-t
windowing now skips PGS like ASS: both formats are fetched once and
consumed whole by their client-side renderers.
This also fixes a pre-existing truncation bug: the -t duration cap was
applied unconditionally, cutting embedded ASS extracts off at the default
600s window even though the ASS client fetches the full track.
Extract the ffmpeg argument construction into streamExtractArgs for
testability, following the buildFFmpegArgs pattern.

* feat(api): expose PGS subtitle tracks as .sup stream URLs
PGS tracks were filtered out of /playback/start subtitle_urls entirely,
so the web player showed no subtitles for PGS-only files (#34). Include
them with a .sup URL extension; DVD/DVB bitmap tracks stay hidden since
they still have no non-burn-in delivery path.
HandleSubtitle streams the full PGS track as application/octet-stream.
The seek/duration window is forced to zero for sup: subtitleSeekPosition
falls back to the session's last reported position even without a
?position= query, which would otherwise start the extract mid-file. The
proxy-node subtitle handler gets the same sup branch, streaming ffmpeg
output directly instead of buffering like its text paths.

* refactor(player): consolidate subtitle codec helpers into subtitleCodecs.ts
Rename assSubtitles.ts to subtitleCodecs.ts — the module already labeled
every codec, not just ASS — and add isPGSCodec/isBitmapCodec. Replace the
duplicated BITMAP_CODECS set in SubtitleTranslateModal with the shared
helper so codec lists live in one place.

* feat(player): native PGS subtitle rendering via libpgs
Render PGS subtitle tracks client-side instead of leaving them
unavailable (#34). usePGSSubtitles mirrors the JASSUB hook: when a PGS
track is active it lazy-loads libpgs, which fetches the .sup stream in a
worker, decodes display sets progressively as bytes arrive, and draws
them onto a canvas positioned over the video.
The renderer looks up the display set at currentTime + timeOffset, so
the HLS stream origin adds and the user-facing delay subtracts — a
positive delay shows subtitles later, matching VTT semantics. Offset
changes apply through the timeOffset setter without recreating the
renderer; track switches, PiP detach, and unmount dispose it.

* feat(player): prefer text over bitmap tracks in subtitle auto-select
With PGS tracks now listed, an earlier PGS track would win auto-select
over a later same-language SRT/ASS track. Deprioritize bitmap codecs
within the same source tier — text is lighter to render and styleable —
while a PGS track still wins when it is the only language match, and
forced-PGS auto-select now works.
