Module locks 

Resource lock registry with full lifecycle.

Provides acquire/release/heartbeat/TTL-expire/startup-cleanup for any scoped resource operation, wired to the typed event system from task 9.

OCP contract

• Adding a new scope dimension: add one optional field to LockScope and one intersection arm in LockScope::intersects. No existing arms change.
• Adding a new release reason: add one ReleaseReason variant. Serializes automatically via rename_all = "snake_case".
• Heartbeat loop works for any scope — it is a generic background task that calls release_stale on any LockRegistry.
• Event emission uses events::emit — no string literals scattered at call sites.
