Stop joining ChipAudio on every EXIT GAME, always rebuild the Gen1 Game
module on Play-again, and treat iOS like Android for return-to-launcher so
release/mobile LOVE restarts no longer wipe Game.load or crash on quit.
Stop fanning out arbitrary field:release() during Game/Game2 reset — shared
modules use :release as a handle API, and that teardown left the Gen1
singleton unbootable (Game:load nil) on Play-again. Harden bootGame and
endGameSession to rebuild the module if load is missing.
- Introduced `teardownMountedSession` to handle cleanup of mounted versions, generated data, and mod states during transitions between the editor and launcher.
- Added `flushEditorPackageLoaded` to evict save-editor modules from `package.loaded` dynamically, ensuring a clean state for subsequent sessions.
- Implemented `Game:reset` and `Game2:reset` methods to clear session-specific fields, allowing for a fresh start when returning to the launcher.
- Enhanced `Renderer` and `TileRenderer` to release GPU resources immediately, preventing memory leaks during rapid transitions.
- Updated `MagnetTrainRide` to support OAM priority overlays and manage background rendering with new shader functionality.
This commit improves the stability and performance of the application during in-process transitions, particularly on Android.
