/api/identity/whoami — returns the resolved identity for the currently
logged-in Clerk user. Used by:
  - frontend UI elements that want to show "Logged in as Mike (admin)"
  - debug verification ("did the right clerk_id make it to the server?")
  - the agent itself, if it ever wants to introspect its own current user
