Fix SEGV crash: Initialize window and font in stateInit()

- Move window initialization and font loading to stateInit()
- Window now opens before splash screens (required for rendering)
- Custom font loaded in stateInit for splash screen use
- Remove RL.config() call from luaCallMain() (window already initialized)
- Remove stateContextInit() call (initialization now done in stateInit)
- Add hasWindow, customFontLoaded, resolution fields to State
- Fix memory management for custom font in stateFree()

This matches the ReiLua-JamVersion architecture where the window
is opened early so splash screens can render properly.
