build: assemble pinned OBS 32.0.4 runtimes for Linux and Windows

Linux builds libobs and an allowlist of official plugins from source in OBS's relocatable layout. Windows copies the official release byte-for-byte so the Game Capture hook keeps its signature. Adds a headless Wayland rig for PipeWire/portal capture tests on machines without a display.
