8f46066a64 feat(perf): add 300-second local cache for variable crypt retrieval (#6483)
* feat: add 60-second cache for workspace key retrieval

This implements a cache with 60-second staleness for the get_workspace_key
function to reduce database queries for workspace encryption keys. The cache
follows the same pattern as the existing CUSTOM_ENVS_CACHE but with a
shorter expiration time.

* Extend cache staleness from 60 to 300 seconds

* feat: add cache invalidation notifications for workspace keys

Add PostgreSQL LISTEN/NOTIFY mechanism to invalidate workspace key cache
across all servers and workers when workspace keys change.

- Add database migration with trigger function for workspace_key changes
- Add notification handler in main.rs to remove from WORKSPACE_KEY_CACHE
- Follow same pattern as existing workspace environment cache invalidation
- Ensures distributed cache consistency for workspace encryption keys
