- Queue setExcludedWords writes so a slower in-flight save can't land after and overwrite a newer edit
- Run server-sync listeners independently so one throwing listener doesn't roll back a successful write or block the rest
- Add regression tests for write ordering, listener isolation, coalesced known-word snapshots, and vocabulary hook aggregate refresh/retry
- Refetch vocabulary summary/charts once the exclusion list write is server-acknowledged, and retry failed aggregate loads with backoff before showing an inline error with a Retry control
- Coalesce concurrent getVocabularySummary calls into a single worker task
- Scan imm_words in id-keyed batches to bound memory for large vocabularies
- Add formatRofiPrompt to trim trailing whitespace and append a single space, keeping the prompt from running into the input field
- Apply it across all rofi -p usages in picker.ts and history-command.ts
- Add tests for formatRofiPrompt edge cases (empty/whitespace-only prompts)
- Extract buildHistoryEntryActions to build the series action menu, now including a previous-episode option alongside replay/next/browse/quit
- Update docs and changelog entry to describe the new option
- Add tests covering previous/replay/next ordering and omission when last watched file is missing
- AnkiConnect proxy now detects EADDRINUSE, logs a warning, and surfaces an overlay notification instead of crashing video startup
- Background AppImage bootstrap runs Chromium with in-process-gpu so no GPU child survives app.exit() and outlives the FUSE mount, fixing the remaining DrKonqi "Service Crash" case
- Add changelog fragment for the proxy fix; update the AppImage quit fragment with the GPU child root cause
- Merge the five separate sync change fragments (launcher command, UI window, close/quit fixes, active-session double-count, monthly rollup timezone) into a single changes/sync.md
- Fold kana-pos-content-classification.md into annotation-noise-rule-table.md
- Drop the now-stale Unreleased sections from CHANGELOG.md and docs-site/changelog.md
- Tweak tsukihime-english-subtitles.md wording
