Consolidates two standalone Railroader mods into one UMM "everything mod"
with an optional-module framework. Modules are disabled by default and
toggled per-module from the S3 settings page.
Core framework:
- IModule contract plus ModuleRegistry, with each module owning a Harmony
instance scoped by its id so only enabled modules patch the game
- Per-module flat JSON settings (SettingsStore). On this Mono runtime
JsonUtility silently drops nested custom-class fields, so settings stay flat
- Foldout-per-module settings panel plus a detector that offers to disable the
old standalone mods if they are still installed
Modules (moved over to parity, verified in-game):
- Physics Optimizer (was RailroaderPhysicsOverhaul): LOD fast-path and
auto-freeze, profiler overlay, debug car tinting, /rpf console commands
- Map Popout (was RRPopout): native map detach window. Pure-UMM install that
drops the winhttp proxy and LoadLibrary's RRPopout.dll from the mod folder.
Native Win32 + D3D11 + Dear ImGui engine included. Fixes a latent break where
the now-private MapBuilder.UpdateForZoom() is reached via Traverse.
Build: dotnet for the managed assembly (netstandard2.1) and CMake for the
native DLL. build-local.ps1 installs into the game, build-release.ps1 packages
the UMM drag-install zip.
