Derek Carr 7f16d60ef1 feat(persistence): implement optimistic concurrency control with CAS (#1292) ...

Add resource_version-based optimistic concurrency control to the
persistence layer. Every write now requires an explicit WriteCondition
(MustCreate or MatchResourceVersion), enforced at compile time by
gating unconditional put/put_message behind #[cfg(test)].

- Add WriteCondition enum and put_if for conditional writes
- Add update_message_cas for atomic read-modify-write operations
- Add list_messages/list_messages_with_selector helpers that hydrate
  resource_version from authoritative DB rows
- Convert all production write paths to CAS-aware methods
- Gate put/put_message behind #[cfg(test)] to prevent non-CAS writes
- Use structured PersistenceError::UniqueViolation matching instead of
  string matching for duplicate detection
- Hydrate resource_version from WriteResult directly on creates,
  eliminating unnecessary read-after-write round trips
