Send message

POST 
/thread/:id/send

Sends a message to a conversation thread. The current user must have reply access. Supports file attachments, message metadata, and offline message sync via temporary IDs. If moderation is enabled, the message enters a pending queue instead of being delivered immediately. The temp_id and temp_time parameters enable offline-first messaging — the server validates that temp_time is within ±600 seconds of server time. After sending, the thread is automatically marked as read for the sender.
