Pull request overview

This PR updates the session middleware to treat PATCH requests as write operations (therefore enforcing the API lock and using an isolated session stack), and adds a focused Jest test suite to validate middleware behavior plus session cleanup helpers.

Changes:

• Extend the “write methods” list to include PATCH, so locked APIs also block PATCH writes.
• Remove the /v1/workloadCatalog early-return special case from write handling.
• Add src/middleware/session.test.ts with unit tests covering read vs write routing, lock behavior, and cleanSession/cleanAllSessions.
