Adventure Contract prototype

Dependency-free TypeScript prototype for Node.js 22.14+ with explicit type stripping.

• adventure-types.ts — genre-neutral HostPreferences, AdventureDraft, and output types.
• adventure.ts — host/draft boundary validation and deterministic compilation.
• adventure-support.ts — trigger derivation and stable contract hashing.
• fixtures/sci-fi-comedy.ts — separate original, non-canonical host brief and planner draft.
• adventure.test.ts — behavioral and adversarial checks.
• demo.ts — executable compile/validate summary.

The fixture is Technical R&D test data, not product canon. It contains no borrowed setting, characters, rules text, or adventure material.
