Delete Economy.Server/Economy.Shared, LiteNetLib, network message types,
the texture-based Gravity duplicate, unreferenced scripts and agent
states, and unused plugins (MSAGL, NaughtyAttributes, AsyncAwaitUtil,
Allegorithmic, Localization samples, MrtTest, ThinkGear, QuickGraph),
plus vendored sample scenes, root zips/logs, and the stray Obsidian
folder. MainMenu logs faulted galaxy-generation tasks directly instead of
AsyncAwaitUtil's WrapErrors. Stop tracking UserSettings and the Wwise
.backup folder; ignore generated .sln/.csproj by pattern.
Game-system test scenes are kept. Playdead stays: VolumeCloudRenderer
derives from its EffectBase.
