test: address runtime nitpick coverage

- Extract filterLegacyMpvPluginFileCandidates, buildYomitanAnkiSettingsKey, setMpvCurrentSecondarySubText, runSupportAssetUpdatesForLauncherResult helpers
- Include forceOverride in yomitan anki settings cache key (was missing, causing incorrect cache hits)
- Detect same-PID stale stats daemon state to avoid self-connect
- Validate non-empty extension in buildFfmpegSubtitleExtractionArgs
- Drop unused message param from showOverlayLoadingStatusNotification
- Log and rethrow on session bindings artifact write failure
- Add unit tests for all extracted helpers

   waits for a fresh measured subtitle rectangle before signaling readiness.
-- If the startup subtitle has no cached annotations yet, autoplay priming emits a raw first-paint
-  subtitle payload before background tokenization. The tokenized payload replaces it when ready, but
-  the visible overlay can paint and measure the line before the mpv startup gate resumes playback.
-- If startup `sub-text` is temporarily empty, autoplay priming refreshes the active subtitle source

 - If mpv is before the first subtitle, SubMiner sends a synthetic warm readiness payload after
   tokenization warmup and visible overlay content-ready. This releases playback without waiting for
   a later subtitle event that cannot happen while mpv is paused.

 - **Runtime:** The bundled Electron runtime is updated from 39.8.6 to 42.2.0.
 
-- **Subtitle Delay Shortcuts:** Default overlay subtitle delay and step bindings now match mpv's own defaults.
-  - `z`, `Z`, and `x` adjust sub-delay; `Ctrl+Shift+Left/Right` runs native sub-step and shows the current delay on the OSD.
-  - The previous SubMiner-only adjacent-cue delay action has been removed.
-
-- **Update Notifications:** New installs default to overlay-only update notifications instead of overlay plus system notifications.
-
 ### Fixed
 
 - **macOS Overlay:** Significantly improved overlay focus and stability across a range of scenarios.
   - The overlay hides when mpv loses focus, is minimized, or is no longer the foreground target; stays stable through transient window-tracking misses; remains correctly layered during stats mouse passthrough; and opens over fullscreen mpv without switching Spaces.
   - Passthrough is fixed so mpv controls stay clickable before hovering a subtitle bar. The compiled mpv window helper is now correctly bundled, preventing the overlay from falling back to a slower startup path on first launch.
-  - Yomitan popup focus is restored after card mining or popup reload; clicking transparent overlay space correctly closes the popup and returns passthrough to mpv without a hide/reappear cycle.
 
 - **Linux/Hyprland Overlay:** Overlay placement refreshes after leaving mpv fullscreen so the visible overlay stays aligned to the player.
   - The overlay stays stacked above mpv after click-to-focus events and is suspended while the in-player stats window is open.
   - Settings windows (SubMiner and Yomitan) now open above the subtitle overlay; the overlay hides immediately when the character dictionary modal opens, including while AniList lookup is in progress.
-  - Auto-paused startup is more reliable: the overlay stays interactive during the first measurement gap, startup subtitle cache misses paint raw text before tokenization finishes, and temporarily empty mpv subtitle reads are resolved before synthetic warm readiness can resume playback.
-
-- **Playback:** The first subtitle is primed before autoplay resumes so the overlay renders text before video playback begins. Launcher-owned videos quit SubMiner when playback ends while background and tray sessions stay alive.
-  - The visible overlay and subtitle stream stay alive after restarting SubMiner from the `y-r` shortcut, with correct Linux bounds reapplication and user-paused playback preserved through readiness gates.
-  - The visible overlay remains active when mpv advances to the next playlist item, even when the next episode loads after the warm transition delay.
 
 - **Jellyfin Playback:** Resolved a wide range of discovery and playback issues: the active item is no longer reloaded during startup, paused mpv is no longer misreported as playing, startup unpause no longer repeats after a manual pause or `y-t` toggle, and duplicate ready signals no longer re-show the overlay.
   - Discovery now correctly handles delayed Japanese subtitle selection and prevents later-loading foreign tracks from stealing the active Japanese track.
@@ -96,7 +84,6 @@
 - **AniList Progress:** Threshold checks now use fresh playback position data so updates fire correctly when playback reaches or skips past the watched threshold.
   - Season-specific results are preferred for multi-season files, with a clear message when the matched season is not in Planning or Watching status.
   - Repeated missing-token checks no longer exhaust AniList retry attempts or create duplicate dead-letter entries for the same episode.
-  - Manual AniList linking from the stats anime page now strips generated `Season N` suffixes from automatic searches so results match the base title correctly.
 
 - **Anki:** Sentence-audio padding is now opt-in by default; animated AVIF freeze-frame duration is correctly aligned to word audio length without double-counting padding.
   - Multi-line sentence mining stays aligned for repeated subtitle text; Kiku duplicate-card detection and merge flow are fixed; clipboard card updates from YouTube use mpv's resolved stream URLs; sentence cards refresh the secondary subtitle before saving.
@@ -110,19 +97,21 @@
 
 - **Updater:** Update checks are more stable across platforms: Linux uses GitHub release metadata; `subminer -u` can update independently of the tray app; macOS update dialogs reliably appear in the foreground.
   - Builds that cannot apply native updates show a manual-install message instead of a restart prompt. Windows retains the native NSIS update path while routing updater HTTP through the main process.
-  - Linux updates now correctly create and refresh the launcher runtime plugin copy and rofi theme alongside AppImage and launcher updates; both support assets are auto-installed from the bundled app on first launch if either is missing.
 
 - **Setup - macOS:** First-run setup recognizes existing `subminer` installs in Homebrew or user PATH directories and avoids writing into Homebrew-owned paths.
   - `subminer app --setup` opens the setup flow even when SubMiner is already running. The standalone setup app quits after completing first-run setup, and `subminer settings` exits cleanly when the window is closed.
 
 - **Tray App:** Fixed several lifecycle issues: the tray stays running when Yomitan settings are closed; a close-only menu prevents accidentally quitting the tray app; an in-page close button is available on Hyprland where native window controls are unavailable.
   - Settings loading no longer blocks other tray actions; the embedded popup preview is disabled to prevent renderer hangs during sidebar navigation; extension refreshes at startup are serialized; the session help modal closes correctly without mpv running.
-  - On Windows, "Open SubMiner Setup" now correctly opens the setup window after first-run setup is complete. System notifications now correctly show the SubMiner app icon when no custom notification image is provided.
+  - On Windows, "Open SubMiner Setup" now correctly opens the setup window after first-run setup is complete.
 
 - **Launcher:** Launcher-opened videos reuse an already-running background SubMiner instance and correctly reapply preferred subtitles on warm launches. Videos stay paused until subtitle priming and tokenization readiness complete.
   - `subminer settings` on macOS no longer emits Electron menu diagnostics and exits cleanly when the window is closed. Linux first-run launcher installs build with a valid Bun shebang; `subminer app` on Linux returns control to the terminal immediately.
   - On Windows, managed mpv launches from a background instance correctly retarget the new mpv socket, bind to the player window, and receive startup overlay options.
 
+- **Playback:** The first subtitle is primed before autoplay resumes so the overlay renders text before video playback begins. Launcher-owned videos quit SubMiner when playback ends while background and tray sessions stay alive.

 - **Subtitle Frequency:** Frequency highlighting is preserved for determiner-led noun compounds like `その場` while standalone determiners are still filtered. Annotations are corrected for Yomitan single-token compounds with internal particles like `目の前`.
