- Add changelog entries for the split-cour AniList season resolution fix and the subsync stream-track fixes
- Document anime browser language filter, stream subtitle download-to-disk behavior, and series/season/episode metadata threading
- Update domain ownership and knowledge-base catalog for the anime browser modules
- Trim the credits table and clarify the M-Extension-Server licensing note in README
Cross-check every config key, shortcut, default, and command against the
current source and fix the drift (mpv.socketPath, auto_start_overlay
default, AniSkip TAB key, JLPT N4 color, secondary-sub font/defaults,
secondary-sub language behavior, modular mpv plugin layout, and more).
Add plain-language intros and first-use definitions across onboarding and
integration pages so non-technical readers can follow along.
Internal docs/: fix stale module paths in architecture/domains.md, add
missing contract entry points and catalog rows, and bump verified dates.
Remove the obsolete docs/plans/ directory (its only plan shipped in
0.15.0) and reframe planning.md so plans live with the work, not in docs/.
