fix(review): address latest CodeRabbit comments

Replace every user-facing "token(s)" label, tooltip, and message in the
stats UI with "words" so the terminology is consistent and friendlier
(e.g. "Words Seen", "word occurrences", "3.4 / 100 words", "Words Today").

-2. Harden the autoplay-ready release path so paused startup keeps retrying until mpv is actually released or media changes, without resuming user-paused playback later.

 ## Implementation Notes
 
 <!-- SECTION:NOTES:BEGIN -->
 Added a small current-media tokenization gate in main runtime. Media changes reset the gate, the first tokenization-ready event marks it ready, and auto-sync now waits on that gate only before Yomitan dictionary inspection/import/settings updates. Snapshot generation and merged ZIP build still run immediately in parallel.

-<!-- SECTION:NOTES:BEGIN -->
-2026-03-20: Created during live debugging of a user-reported stale anime profile picture after changing the AniList entry from the stats UI.
-2026-03-20: Root cause was in `upsertCoverArt(...)`. When a row already had `cover_blob_hash`, a later AniList reassignment with a freshly downloaded cover reused the existing hash instead of hashing the new bytes, so the blob store kept serving the old image while metadata changed.
-2026-03-20: Added a regression in `src/core/services/immersion-tracker-service.test.ts` that reassigns the same anime twice with different fetched image bytes and asserts the resolved anime cover changes to the second blob while both videos still deduplicate to one shared hash.
-2026-03-20: Fixed `src/core/services/immersion-tracker/query.ts` so incoming cover blob bytes compute a fresh hash before falling back to an existing row hash. Existing hashes are now reused only when no new bytes were fetched.

-<!-- SECTION:FINAL_SUMMARY:BEGIN -->
-Fixed stale anime cover art after AniList reassignment by correcting cover-blob hash replacement in the immersion tracker storage layer. Reassignments now store the new fetched image bytes instead of reusing the previous blob hash from the row, while still deduplicating the updated image across videos in the same anime.
-
-Added focused regression coverage that reproduces the exact failure mode: same anime reassigned twice with different cover downloads, with the second image expected to replace the first. Verified with the touched service test file plus the SubMiner `core` verification lane.

-
-Anime episode progress can still show `0%` for older sessions that have watch-time and subtitle timing but no persisted `ended_media_ms` checkpoint. Recover progress from the latest retained subtitle/event segment end so already-recorded sessions render a useful progress percentage.
-
-## Acceptance Criteria

-- [x] Existing ended-session metrics and aggregation totals do not regress.
-- [x] Regression coverage locks the fallback behavior.
-
-## Implementation Notes
-
-Added a query-side fallback for anime episode progress: when the newest session for a video has no persisted `ended_media_ms`, `getAnimeEpisodes` now uses the latest retained subtitle-line or session-event `segment_end_ms` from that same session. This recovers useful progress for already-recorded sessions that have timing data but predate or missed checkpoint persistence.

-## Description
-
-<!-- SECTION:DESCRIPTION:BEGIN -->
-`subminer` mpv auto-start on mac can stall before the video is usable because the helper process launched with `--texthooker` still runs heavy app-ready startup. Recent logs show the helper loading the Yomitan Chromium extension, emitting `Permission 'contextMenus' is unknown` warnings, then hitting Chromium runtime errors before SubMiner signals readiness back to the mpv plugin. The texthooker helper should take the minimal startup path needed to serve texthooker traffic without loading overlay/window-only startup work that can crash or delay readiness.
-<!-- SECTION:DESCRIPTION:END -->
-
-## Acceptance Criteria
-<!-- AC:BEGIN -->
-- [x] #1 Launching SubMiner with `--texthooker` avoids heavy app-ready startup work that is not required for texthooker helper mode.
-- [x] #2 A regression test covers texthooker helper startup so it fails if Yomitan extension loading is reintroduced on that path.
-- [x] #3 The change preserves existing startup behavior for non-texthooker app launches.
-<!-- AC:END -->
-
-## Implementation Notes
-
-<!-- SECTION:NOTES:BEGIN -->
-Follow-up: user confirmed the root issue is the plugin auto-start ordering. Adjust mpv plugin sequencing so `--start` launches before any separate `--texthooker` helper, then verify plugin regressions still pass.
-<!-- SECTION:NOTES:END -->
-
-## Final Summary
-
-<!-- SECTION:FINAL_SUMMARY:BEGIN -->
-Fixed the mac mpv startup hang caused by the `--texthooker` helper taking the full app-ready path. `runAppReadyRuntime` now fast-paths texthooker-only mode through minimal startup (`reloadConfig` plus CLI handling) so it no longer loads Yomitan or first-run setup work before serving texthooker traffic. Added regression coverage in `src/core/services/app-ready.test.ts`, then verified with `bun test src/core/services/app-ready.test.ts src/core/services/startup.test.ts`, `bun test src/cli/args.test.ts src/main/early-single-instance.test.ts src/main/runtime/stats-cli-command.test.ts`, and `bun run typecheck`.

-## Description
-
-<!-- SECTION:DESCRIPTION:BEGIN -->
-During startup on mpv auto-start, character dictionary regeneration/update can be active while playback remains paused. The current startup OSD sequencer buffers dictionary progress behind annotation-loading OSD, which leaves the user with no visible dictionary-specific progress while the pause is active. Adjust the startup OSD sequencing so dictionary progress can surface once tokenization is ready during the paused startup window, without regressing later ready/failure handling.
-<!-- SECTION:DESCRIPTION:END -->
-
-## Acceptance Criteria
-<!-- AC:BEGIN -->
-- [ ] #1 When tokenization is ready during startup, later character dictionary progress updates are shown on OSD even if annotation-loading state is still active.
-- [ ] #2 Startup OSD completion/failure behavior for character dictionary sync remains coherent after the new progress ordering.
-- [ ] #3 Regression coverage exercises the paused startup sequencing for dictionary progress.
-<!-- AC:END -->
-
-## Implementation Notes
-
-<!-- SECTION:NOTES:BEGIN -->
-2026-03-20: Confirmed issue is broader than OSD-only. Paused-startup OSD fixes remain relevant, but current user report also points at a regression in non-blocking startup playback release (tracked in TASK-143).
-
-2026-03-20: OSD sequencing fix remains in local patch alongside TASK-143 regression fix. Covered by startup-osd-sequencer tests; pending installed-app/mpv validation before task finalization.

+
+# Incremental Known-Word Cache Sync
+
+## Goal
+
+Stop rebuilding the entire known-word cache on startup or routine refreshes. Keep the cache correct through incremental reconciliation on the configured sync cadence, with an immediate append path for freshly mined cards.
+
+## Scope
+
+- Persist per-note extracted known-word snapshots beside the existing global `words` list.
+- Replace startup refresh with load-only behavior.
+- Make timed refresh diff current Anki note IDs against cached note IDs, then apply add/remove/edit deltas.
+- Add `ankiConnect.knownWords.addMinedWordsImmediately`, default `true`.
+- Keep full rebuild out of normal lifecycle; reserve it for explicit doctor tooling.
+
+## Data Model
+
+Persist versioned cache state with:
+
+- `words`: deduplicated global known-word set for stats/UI consumers
+- `notes`: record of `noteId -> extractedWords[]`
+- `refreshedAtMs`
+- `scope`
+
+The in-memory manager derives the global set from the per-note snapshots during sync updates so deletes and edits can remove stale words safely.
+
+## Sync Behavior
+
+- Startup: load persisted state only
+- Interval tick or explicit refresh command: run incremental sync
+- Incremental sync:
+  - query tracked note IDs for configured deck scope
+  - remove note snapshots for note IDs that disappeared
+  - fetch `notesInfo` for note IDs that are new or need field reconciliation
+  - compare extracted words per note and update the global set
+
+## Immediate Mining Path
+
+When SubMiner already has fresh `noteInfo` after mining or updating a note, append/update that note snapshot immediately if `addMinedWordsImmediately` is enabled.
+
+## Verification
+
+- focused cache manager tests for add/delete/edit reconciliation
+- focused integration/config tests for startup behavior and new config flag
+- config verification lane because defaults/schema/example change
