feat: Add Spear of Destiny demo support with dedicated asset registry and entity definitions

Browse Source 
- Introduced SpearDemoAssetRegistry for managing assets specific to the Spear of Destiny demo.
- Created SpearDemoEntityModule to define enemy animations with adjusted sprite ranges.
- Implemented SpearDemoHudModule and SpearDemoMenuPicModule for HUD and menu assets.
- Added SpearDemoSfxModule for sound effect mappings specific to the demo version.
- Updated enemy classes (Guard, Mutant, Officer, SS) to support custom animation sets.
- Modified entity registry to accept a custom AssetRegistry for spawning entities.
- Enhanced rendering with CRT phosphor bloom effect in GLSL shaders.
- Adjusted ASCII and software renderer layouts for improved UI spacing.
- Added tests for SpearDemoAssetRegistry to ensure correct asset resolution and enemy spawning.
