feat(m6): PowerMizer + Wine/Steam versions + non-Steam launchers — 0.22.0

M6 leftovers (the watcher defers to M9's trigger-mode work):
- gameenv: check_gpu_powermizer (NVIDIA, X; degrades when the gpu target won't
  resolve), check_wine (wine --version), check_steam_client (dpkg package version);
  steam.client_version() helper.
- core/launchers.py: detect Lutris (read-only SQLite pga.db) and Heroic (Epic
  legendary + GOG JSON) installed games; Game gained a `launcher` field.
- Games page + `rigdoctor games` list non-Steam games alongside Steam, tagged by
  launcher; Run Diagnostic works on them (auto-launch stays Steam-only).
- Tests for launchers (synthetic Lutris db + Heroic json).
