feat(games): manually add games (e.g. SPT) with launch + own logs

Some titles never show up in a Steam/Lutris/Heroic scan — standalone mod
launchers like SPT (Single-Player Tarkov), itch.io downloads, hand-installed
executables. Add a user-authored custom-games list (core/customgames.py) shown
alongside the other sources in `rigdoctor games` and the GUI.

Each entry can carry a launch command and a log directory:
  - `rigdoctor games add "SPT" --command .../tarkov.sh` (logs/ auto-detected)
  - `rigdoctor games play "SPT"` launches it under the crash-capture wrapper
    (wrap.run gains an explicit game-name override, since there's no SteamAppId)
  - the diagnostic now feeds the game's own logs to the analysis: gamelogs
    .collect(game=...) tails the registered log dir (SPT's server/launcher logs)
    alongside the kernel log, freshness-scoped by mtime.
