fix(jellyfin): show overlay, inject plugin, and fix stats title on playback (#77)

* fix(jellyfin): show overlay, inject plugin, and fix stats title on playb

- Show visible overlay automatically during Jellyfin playback so subtitleStyle applies
- Inject bundled mpv plugin on auto-launch so keybindings work without overlay focus
- Group Jellyfin playback stats under item metadata (jellyfin://host/item/id) instead of stream URLs so episodes merge with matching local titles
- Mark ffsubsync unavailable in subsync modal for remote media paths
- Drain queued second-instance commands even when onReady throws

* fix(overlay): stabilize macOS focus handoff and sidebar Yomitan pause

- Keep overlay visible during macOS foreground probe after overlay blur
- Hold sidebar hover-pause while a Yomitan lookup popup remains open

* fix(jellyfin): fix discovery loop, device identity, tray state, and Disc

- Derive device identity from OS hostname; remove legacy configurable client/device fields
- Prevent discovery playback from reloading active item, misreporting pause state, and duplicate overlay restores
- Restart stale tray discovery sessions without re-login when server drops SubMiner cast target
- Sync tray discovery checkbox state on Linux after CLI/startup/remote-session changes
- Stop Discord presence falling back to stream URLs; prime title before tokenized stream loads
- Fix picker library discovery when log level is above info
- Fix config.example.jsonc trailing commas and array formatting

* docs(release): trim and consolidate prerelease notes for 0.15.0

- Remove breaking changes section and several redundant bullet points
- Consolidate per-platform updater notes into a single entry
- Normalize em-dash separators to hyphens in section headers

* fix(config): remove trailing commas from config.example.jsonc

- Strip trailing commas throughout both config.example.jsonc copies
- Reformat inline arrays to multi-line for JSON strictness
- Update Jellyfin subtitle preload and playback launch tests and impl

* fix(tokenizer): preserve known-word highlight when POS filters suppress

- Known-word cache matches now set isKnown=true even for tokens excluded by POS filters
- POS exclusion gate suppresses N+1, frequency, and JLPT only; known status is computed before the gate
- Jellyfin subtitle preload continues after cleanup failures instead of aborting
- Update config docs and option description to document the known-word bypass behavior

* fix(jellyfin): send explicit hide/show overlay instead of toggle

- Track overlay visibility in plugin state; y-t uses explicit hide/show commands when state is known
- Prevent paused Jellyfin playback from resuming on overlay hide
- Fix subtitle cache cleanup to only remove dirs after successful cleanup

* fix(jellyfin): fix remote progress sync, seek reporting, and startup sto

- arm active playback before loadfile with loadedMediaPath: null to suppress premature stop events
- force immediate progress report on seek-like position jumps at the mpv time-pos level
- send positionTicks and failed=false in reportStopped payload
- remove EventName from HTTP timeline payloads (websocket-only field)
- add startup grace window to drop stop events before media finishes loading

* fix(jellyfin): fix overlay toggle sync, redirect reload, and AppImage bi

- Sync visible-overlay state back to plugin via script messages to avoid toggle/hide drift
- Collapse duplicate toggle events within 250ms to prevent hide-then-show on single keypress
- Preserve manual hide across Jellyfin path-changing redirects even when media-title drops
- Rearm managed subtitle defaults on path-changing redirects
- Route toggleVisibleOverlay session binding through plugin toggle instead of app-side IPC
- Show Linux/Hyprland overlay passively (showInactive) to avoid stealing mpv keyboard focus
- Fix AppImage binary resolution to prefer $APPIMAGE env over mounted inner binary
- Add stats window layer management so delete/update dialogs appear above stats window
- Fix Jellyfin remote progress sync during Linux websocket reconnect windows

* Fix CodeRabbit review feedback

* fix(jellyfin): subtitle timing, resume progress, and overlay sync

- Add per-stream subtitle delay persistence and auto timeline-offset correction
- Strip server-selected subtitle stream from mpv load URL; suppress plugin subtitle rearm and auto-start during app-managed preload
- Fix resume position lost when mpv resets on stop; use last known position for final progress/stopped reports
- Keep Play vs Resume distinct to avoid early seek race on normal play
- Fix discovery resume when remote play sends StartPositionTicks=0 despite saved progress
- Deduplicate show/hide overlay commands using recorded visibility state
- Rewrite docs-site Jellyfin page around cast-to-device UX

* test: update lifecycle cleanup assertion

* fix: clear aborted playback state, fix overlay passthrough, and guard du

- Reset app_managed_playback_pending on lifecycle cleanup to prevent state leak into next item
- Record visible overlay action only after command succeeds, not before
- Non-native passive overlay now always click-through on re-show (fix isNonNativePassiveOverlay ordering)
- Defer activeParsedSubtitleMediaPath assignment until after prefetch completes
- Move autoplay gate release into the hide branch of toggleVisibleOverlay
- Clear active Jellyfin playback when stopping media that never loaded
- Reset managed subtitle delay and delay key when no external tracks are available
- Await async removeDir in subtitle cache cleanup
- Guard duplicate delete clicks in MediaDetailView and SessionsTab with refs
- Escape key in DeleteConfirmDialog now calls stopPropagation and stopImmediatePropagation
