The chat-sdk bridge was emitting inbound messages with a nested
author.{userId,fullName,userName} shape, but router.ts:extractAndUpsertUser
reads flat content.senderId / sender / senderName. Result: every chat-sdk
adapter (telegram, discord, slack, teams, gchat, webex, matrix, resend,
imessage, whatsapp-cloud) hit the strict access gate with userId=null and
got dropped, even for the registered owner.
Project author into the flat fields inside messageToInbound so the bridge
matches the contract documented at router.ts:14-17. Native adapters
already set these directly.
