- Block unsupported or downgraded Electron runtimes before loading profile storage
- Isolate development profiles and guard against unexpected dictionary loss
- Stop deleting imm_daily_rollups/imm_monthly_rollups on unrelated schema version bumps; their source session/telemetry rows may already be pruned, so deleted buckets could not be rebuilt
- Run startup session-rollup maintenance before the lexical rollup backfill takes the write lock, so recovery no longer races playback writes
- Update the vocabulary summary totals changelog fragment to reflect that watch-time, activity, efficiency, and library charts are no longer cleared during rebuilds
- 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
