feat(tokenizer): use Yomitan word classes for subtitle POS filtering (#57)

* feat(tokenizer): use Yomitan word classes for subtitle POS filtering

- Carry matched headword wordClasses from termsFind into YomitanScanToken
- Map recognized Yomitan wordClasses to SubMiner coarse POS before annotation
- MeCab enrichment now fills only missing POS fields, preserving existing coarse pos1
- Exclude standalone grammar particles, して helper fragments, and single-kana surfaces from annotations
- Respect source-text punctuation gaps when counting N+1 sentence words
- Preserve known-word highlight on excluded kanji-containing tokens
- Add backlog tasks 304 (N+1 boundary bug) and 305 (wordClasses POS, done)

- return a cancel handle from the Linux refresh burst scheduler
- clear pending refresh bursts when overlays hide or windows close
- tighten the burst test polling to wait for the async refresh

* fix: suppress N+1 for kana-only candidates and fix minSentenceWords coun

- Treat kana-only tokens with surrounding subtitle punctuation (…, ―, etc.) as kana-only so they are not promoted to N+1 targets
- Exclude unknown tokens filtered from N+1 targeting from the minSentenceWords count so filtered kana-only unknowns cannot satisfy sentence length threshold
- Add regression tests for kana-only candidate suppression and filtered-unknown padding cases

* Suppress subtitle annotations for grammar fragments

- Use a pure-kana fixture for the subtitle token N+1 case
- Update task notes for the latest CodeRabbit follow-up

* Fix managed playback exit and tokenizer grammar splits

- Ignore background stats daemons during regular app startup
- Split standalone grammar endings before applying annotations
- Clear helper-span annotations for auxiliary-only tokens

* fix: refresh current subtitle after known-word mining

* fix: suppress sigh interjection annotations

* fix: preserve jlpt underline color after lookup

* Replace grammar-ending permutations with shared matcher; preserve word a

- Extract `grammar-ending.ts` with `isStandaloneGrammarEndingText` / `isSubtitleGrammarEndingText` pattern matchers
- Replace `STANDALONE_GRAMMAR_ENDINGS` set in parser-selection-stage with shared matcher
- Replace generated phrase sets in subtitle-annotation-filter with shared matcher
- Remove stale duplicate subtitle-exclusion constants and helpers from annotation-stage
- Manual clipboard card updates now write only to the sentence audio field, leaving word/expression audio untouched

* fix: CI changelog, annotation options threading, and Jellyfin quit

- Thread `TokenizerAnnotationOptions` through `stripSubtitleAnnotationMetadata` so `sourceText` is honored
- Include `jellyfinPlay` in `shouldQuitOnDisconnectWhenOverlayRuntimeInitialized` predicate
- Make mouse test `elementFromPoint` stubs coordinate-sensitive
- Make Lua test `.tmp` mkdir portable on Windows

* Preserve overlay across macOS flaps and mpv playlist changes

- keep visible overlays alive during transient macOS tracker loss
- reuse the running mpv overlay path on playlist navigation
- update regression coverage and changelog fragments

* fix: restore stats daemon deferral

* fix: keep subtitle prefetch alive after cache hits

* Fix JLPT underline color drift and AniList skipped-threshold sync

- Replace JLPT `text-decoration` underlines with `border-bottom` so Chromium selection/hover cannot repaint them to another annotation's color
- Lock JLPT underline color for combined annotation selectors (known, n+1, frequency) and character hover/selection states
- Trigger AniList post-watch check on every mpv time-position update to catch skipped completion thresholds
- Fall back to filename-parser season/episode when guessit omits them

* fix: address coderabbit feedback

* fix: sync AniList after seeked completion

- Report known-word cache clears as mutations during immediate append when state existed
- Add regression tests for each fix

* fix: stop AniList setup reopening on Linux when keyring token exists

- Gate setup success on token persistence: `saveToken` now returns `boolean`; on failure, keeps the setup window open instead of reporting success
- Config reload passes `allowSetupPrompt: false` so playback reloads don't re-open the setup window
- Add regression test for persistence-failure path

* fix: suppress known highlights for subtitle particles

* fix: retry transient AniList safeStorage failures

* fix: hide overlay focus ring

* fix: align Hyprland fullscreen overlays

* fix: restore subtitle playback keybindings

* fix: align Hyprland overlay windows to mpv and stop pinning them

- Force-apply exact Hyprland move/resize/setprop dispatches when bounds are provided
- Stop pinning overlay windows; toggle pin off when Hyprland reports pinned=true
- Compensate stats overlay outer placement for Electron/Wayland content insets
- Make stats overlay window and page opaque so mpv cannot show through transparent insets

* fix: map openCharacterDictionary session action to --open-character-dict

- Add missing Lua CLI dispatch entry for openCharacterDictionary
- Add regression test for Alt+Meta+A binding and CLI flag forwarding

* fix: keep macOS overlay interactive while mpv remains active

- Overlay no longer hides or becomes click-through during tracker refreshes when mpv is the focused window

- Add regression tests for active-mpv tracker refresh and transient tracker-not-ready paths

* fix: address coderabbit subtitle follow-ups

* fix: resolve media detail from sessions when lifetime summary is absent

- Change `getMediaDetail` JOIN to LEFT JOIN on `imm_lifetime_media` and fall back to aggregated session metrics when no lifetime row exists
- Add filter `AND (lm.video_id IS NOT NULL OR s.session_id IS NOT NULL)` to keep results valid
- Add regression test covering the session-visible / media-detail-missing mismatch

* fix: address PR-57 CodeRabbit findings and CI failures

- use filtered word counts in media detail session token aggregation
- cancel fullscreen refresh burst on exit via updateLinuxMpvFullscreenOverlayRefreshBurst
- guard Hyprland JSON.parse in try/catch; exclude windowtitle from geometry events
- narrow focus suppression from :focus to :focus-visible
- apply JLPT lock selectors to word-name-match tokens (N1–N5)

* fix: macOS overlay z-order and Yomitan compound token known highlighting

- Release always-on-top when tracked mpv loses foreground on macOS
- Skip visible overlay blur restacking on macOS to avoid covering unrelated windows
- Prefer Yomitan internal parse tokens over fragmented scanner output for known-word decisions
- Add regression tests for both behaviors

* fix: macOS visible-overlay blur no longer invokes Windows-only blur call

- Split win32/darwin branches in handleOverlayWindowBlurred so darwin visible blur returns early without calling onWindowsVisibleOverlayBlur
- Add regression test asserting Windows callback stays inactive on macOS visible overlay blur
- Close TASK-347

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+SubMiner visible overlay is slightly below mpv when mpv is fullscreen on Linux Hyprland. Align overlay bounds with mpv fullscreen client/monitor bounds.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Hyprland fullscreen mpv overlay uses top-aligned geometry instead of inheriting a downward offset.
+- [x] #2 Regression coverage captures the fullscreen Hyprland geometry case.
+- [x] #3 Targeted tests pass.
+<!-- AC:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Added follow-up Hyprland placement handling after the fullscreenClient geometry fix. SubMiner overlay/stats windows now get stable titles and, on Hyprland, are resolved from `hyprctl -j clients` by current PID/title, then set floating before bounds are applied. The stats overlay reapplies bounds after showing because Hyprland cannot see the hidden window before it is mapped.
+
+2026-05-04 follow-up: offset remains after removing pinning. User reports stats modal still has a top gap from mpv in Hyprland fullscreen. Need inspect exact stats overlay CSS/window bounds after float-only placement.
+
+2026-05-04 follow-up fix: stats CSS already had zero body margin, so the remaining gap points at native Hyprland placement after float-only handling. Added exact `movewindowpixel`/`resizewindowpixel` Hyprland dispatches using the same tracked mpv bounds passed to Electron.
+
+2026-05-04 second follow-up: live `hyprctl -j clients` showed the SubMiner client was already full monitor size at `[0,0]`, so the remaining visible top strip was inside Electron's transparent stats surface rather than compositor geometry. Made the stats overlay BrowserWindow opaque with the stats base background. Also prevented page titles from overwriting the stable SubMiner overlay/stats titles used for Hyprland client matching.
+
+2026-05-04 third follow-up: user confirmed native overlay placement is correct and the remaining gap is stats-page-specific. Made stats overlay mode paint an opaque full-viewport root/background and constrained the stats app to `h-screen` with an internal scrolling main pane, so the overlay page itself covers the mpv frame from y=0.
+
+2026-05-04 fourth follow-up: live Hyprland data showed mpv and SubMiner shared the same outer geometry while stats content still rendered lower. Stats window placement now compensates for Electron/Wayland content insets using `getContentBounds()` versus `getBounds()`, then sends the adjusted outer bounds to Hyprland exact placement so the content area, not just the native surface, aligns to mpv.
+
+2026-05-04 fifth follow-up: user confirmed the offset is Hyprland-fullscreen-only and not present while mpv is windowed. Added Hyprland `setprop` decoration cleanup during exact overlay placement (`rounding 0`, `border_size 0`, `no_shadow 1`, `no_blur 1`, `decorate 0`) because fullscreen mpv has square fullscreen edges while a floating SubMiner stats window can retain Hyprland floating-window decoration.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Summary:
+- Treated Hyprland `fullscreenClient` as a fullscreen signal when resolving mpv overlay geometry.
+- Added Hyprland window placement handling so SubMiner overlay/stats windows are set floating before bounds are applied.
+- Added exact Hyprland move/resize dispatches so floating overlay/stats windows are force-aligned to the tracked mpv bounds.
+- Gave overlay/stats windows stable titles for Hyprland client matching, and reapplied stats bounds after show.
+- Locked overlay/stats window titles against page title changes and made the stats overlay window opaque so mpv cannot show through transparent Electron insets.
+- Made the stats overlay page paint an opaque full-viewport background and added CSS regression coverage for overlay mode.
+- Compensated stats overlay outer placement for Electron/Wayland content insets.
+- Disabled Hyprland floating-window decoration for exact overlay placement over fullscreen mpv.
+- Added regression coverage for the 28px fullscreen geometry shape and Hyprland placement dispatches.
+- Added a changelog fragment for the overlay fix.
