Implemented headless mode using MinimalPlugins and ScheduleRunnerPlugin
to enable running the app without rendering, controlled via Unix socket.
Changes:
- Added conditional compilation based on 'headless' feature flag
- Use MinimalPlugins with 60 FPS ScheduleRunner in headless mode
- Skip rendering plugins (Camera, Rendering, DebugUI, SessionUI)
- Made cube mesh/material assets optional for headless spawning
- Direct NetworkingPlugin + PersistencePlugin instead of MarathonPlugin
- Use app.run() instead of platform executor in headless mode
This enables:
- Running multiple instances for multi-client testing
- Automated testing via marathonctl without GUI overhead
- Background server instances for development
- CI/CD integration for networking tests

The session UI panel was not updating when networking started via
control socket because poll_engine_events used commands.insert_resource
which queued updates until end of schedule. The UI could run before
the command was applied.
Fixed by:
- Initialize CurrentSession at startup in offline state (session.rs)
- Use direct ResMut mutation in poll_engine_events (engine_bridge.rs)
- Check session.state instead of resource existence (session_ui.rs)
This ensures Bevy's change detection triggers immediately when engine
events update the session state.

now the entire networking and persistence stack is zero-copy with
single-allocation, single-copy reads.
