Add ContentSlug component for stable content identity across save/load. Add walk-away KG recording with IncompleteInteraction events per D-064 three-phase consequences. Bump protocol to v8 with DialogueResponseEvent. Fixes #305, #427, #452.

charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
