The first slice of M6 (gaming-environment checks): detect a user's Steam
libraries and the games installed in each — also the D12 "pick a game"
foundation.
- core/steam.py: multi-install/library discovery (libraryfolders.vdf, symlink
dedupe, native/Flatpak/Snap), appmanifest_*.acf scan with runtime/Proton/
redist filtering, scan cache + new-game diff. Stdlib only. VDF keys read
case-insensitively (e.g. lastupdated vs SizeOnDisk).
- Libraries are opt-in (config steam_libraries); the flat TOML writer now
emits list/array values.
- GUI Games page: library checkboxes with per-library counts, game list,
background rescan on every launch, NEW badge + sidebar count for games
installed since the last scan (acknowledged when viewed).
- CLI: rigdoctor games / games libraries [--enable|--disable|--all|--json]
(headless-complete, D17).
- Tests for VDF parse, scan, tool filter, cache diff, config list round-trip.
- Docs (MODULES/ROADMAP) updated; version 0.7.3 -> 0.8.0.
