Add Demo bootstrap + feature flags + trailer music generator
Unity side: AIApocalypse.Demo namespace foundation for the two demo
Unity side: AIApocalypse.Demo namespace foundation for the two demo modes that ship pre-launch (Player Demo for the Steam demo listing, Claude Demo for footage capture). DemoBootstrap parses CLI args before the first scene loads and routes to the right mode.
Build defines:
- DEMO_BUILD — required for any demo code to compile in. Strip from retail.
- PLAYER_DEMO_BUILD — forces player-demo mode without the CLI flag; used by the Steam demo build target.
- CLAUDE_DEMO_BUILD — required for —claude-demo to be honored. Strip from public demo build so footage capture can never be reached by a player.
DemoFeatureFlags is the single place gameplay code asks about demo
behavior — RestrictToAct1, LockHigherDifficulties, etc. — so the
rest of the codebase doesn’t sprinkle if (isDemo) checks.
Tools side: generate_trailer_music.py uses ElevenLabs Music API to produce 3 variations of a 60s Doom Eternal-style techno-metal track for the simple gameplay trailer. Already run once; outputs at tools/test_output/music/trailer/.
