Add web-playable WASM demo with BSP dungeon crawler

Browse source 
- Create self-contained demo game script (src/scripts_demo/game.py) showcasing:
  BSP dungeon generation, Wang tile autotiling, FOV with fog of war,
  turn-based bump combat, enemy AI, items/treasure, title screen
- Add MCRF_DEMO CMake option for building with demo scripts
- Add web/index.html landing page with dark theme, controls reference,
  feature list, and links to GitHub/Gitea
- Build with: emcmake cmake -DMCRF_SDL2=ON -DMCRF_DEMO=ON -DMCRF_GAME_SHELL=ON

Note: Makefile wasm-demo/serve-demo targets also added locally but Makefile
is gitignored. Use CMake directly or force-add the Makefile to track it.
