feat: expand hot-reload to logging, jimaku, subsync, and Anki sub-fields

- Mark logging.level, stats keys, jimaku.*, subsync.*, and granular ankiConnect fields (knownWords, nPlusOne, fields, isLapis, isKiku, behavior) as hot-reloadable
- Refactor classifyConfigHotReloadDiff to path-walk diffing instead of per-key branches
- Wire setLogLevel, invalidateTokenizationCache, refreshSubtitlePrefetch, refreshCurrentSubtitle into hot-reload applied handler
- Exclude ai.* and ankiConnect.ai.* prefixes from config window; hide fields.translation
- Update docs and config.example.jsonc hot-reload annotations
