Gate subtitle name highlighting on character dictionary setting

- Disable `getNameMatchEnabled` when `anilist.characterDictionary.enabled` is false
- Wire character-dictionary enablement into main subtitle tokenization deps
- Add runtime deps test coverage and record task/plan docs

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Ensure subtitle tokenization and other annotations continue to work, but character-name lookup/highlighting is disabled whenever the AniList character dictionary feature is disabled. This avoids unnecessary name-match processing when the backing dictionary is unavailable.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 When anilist.characterDictionary.enabled is false, subtitle tokenization does not request character-name match metadata or highlight character names.
+- [x] #2 When anilist.characterDictionary.enabled is true and subtitleStyle.nameMatchEnabled is true, existing character-name matching behavior remains enabled.
+- [x] #3 Subtitle tokenization, JLPT, frequency, and other non-name annotation behavior remain unchanged when character dictionaries are disabled.
+- [x] #4 Automated tests cover the runtime gating behavior.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add a failing test in `src/main/runtime/subtitle-tokenization-main-deps.test.ts` proving name-match enablement resolves to false when `anilist.characterDictionary.enabled` is false even if `subtitleStyle.nameMatchEnabled` is true.
+2. Update `src/main/runtime/subtitle-tokenization-main-deps.ts` and `src/main.ts` so subtitle tokenization only enables name matching when both the subtitle setting and the character dictionary setting are enabled.
+3. Run focused Bun tests for the updated runtime deps and subtitle processing seams.
+4. If verification stays green, check off acceptance criteria and record the result.
+
+Implementation plan saved in `docs/plans/2026-03-06-character-name-gating.md`.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Created plan doc `docs/plans/2026-03-06-character-name-gating.md` after user approved the narrow runtime-gating approach. Proceeding with TDD from the subtitle tokenization main-deps seam.
+
+Implemented the gate at the subtitle tokenization runtime-deps boundary so `getNameMatchEnabled` is false unless both `subtitleStyle.nameMatchEnabled` and `anilist.characterDictionary.enabled` are true.
+
+Verification: `bun test src/main/runtime/subtitle-tokenization-main-deps.test.ts`, `bun test src/core/services/subtitle-processing-controller.test.ts`, `bun run typecheck`.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Character-name lookup/highlighting is now suppressed when the AniList character dictionary is disabled, while subtitle tokenization and other annotation paths remain active. Added focused runtime-deps coverage and wired the main runtime to pass the character-dictionary enabled flag into subtitle tokenization.
