test(simulation): sprint 8 test suite — pause guards, registry, boundary, determinism
Add 50+ tests: pause guard suite (movement, unpause, roundtrip, stance, interact, batch, tick_rate), EntityRegistry lifecycle (stale mapping, re-register, unknown unregister), boundary value encode/roundtrip (41 values), encoding asymmetry (GDScript signed→Rust unsigned), malformed batch rejection, determinism gauntlet (20-tick replay), per-fix determinism unit tests, and recognition monologue integration tests. Fix pause guard to block all actions except Pause/Unpause while paused. Fixes #461-463, #466-469, #471-473, #479. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
