fix: only process assistant messages in before_message_write

Browse Source 
before_message_write fires for both user (incoming) and assistant
(outgoing) messages. Without a role check, end symbols from other
agents' incoming messages incorrectly trigger turn advances.

Add role check to skip non-assistant messages early.
