fix(simulation): address PR #85 review — warnings and polish items

- Ticker rotation: document sliding-window semantics (vs modulus-aligned)
- Ticker zone ID: add warning about Gauntlet vs production zone ID mismatch
- Proof-room movement profile: respect archetype instead of hardcoding smuggler
- Storyteller tie-break: use exact f32 equality (inputs are discrete integers)
- Observer: .map().flatten() → .and_then() (clippy strict)
- Content loader: remove dangling doc comment before section header
- Tests: replace assert!(false, ...) with TODO comments in ignored tests
- Tests: add frame limiter note on 302-update loop in tell expiry test
