anti 257857338c fix(api): replace threading.Lock with asyncio.Lock for hydration guard ...

await inside a threading.Lock yields to the event loop while the OS
thread still holds the lock — potential deadlock under FastAPI thread
pool dispatch. asyncio.Lock is the correct primitive for async
critical sections. Also fixed stale diurnal.py docstring that had the
delegation direction backwards.
