Fix: deadlock in /clear endpoint — move write_status() outside events_lock

write_status() calls get_current_state() which re-acquires events_lock.
Calling it inside the `with events_lock:` block caused the same thread to
block forever (threading.Lock is not reentrant). Any /clear request would
hang the aggregator indefinitely, breaking detector recovery flow.

Bump to v2.3.2.
