* feat(subtitles): generate Japanese subtitles during Jellyfin playback
- Read the item's original file via toJellyfinOriginalStreamUrl and write output to a temp dir
- Transcoded playback uses Jellyfin's audio index and only external references
- Show Jellyfin media by title and redact URL tokens in subprocess errors
- Update overlay copy, docs, and changelog fragment
* fix(subtitles): redact full stream tokens and reuse one Jellyfin output folder
* test(subtitles): make Jellyfin output path assertions platform-neutral
- Compare dirname/basename via node:path instead of POSIX-only regexes
- Assert the full sub-add command uses the generated output path
- Pages now start with setup and usage, and reference material is in compact tables
- Configuration reference gives each config block a short explanation and a key/default table
- Internal detail removed from user pages, and docs that had drifted from current behavior fixed
- The status line shows today's date, set on the client, instead of the page's last-updated date
- Add changelog fragment
