feat: fire CHAT_MSG_ADDON for inter-addon communication messages

Detect addon messages in the SMSG_MESSAGECHAT handler by looking for
the 'prefix\ttext' format (tab delimiter). When detected, fire
CHAT_MSG_ADDON with args (prefix, message, channel, sender) instead
of the regular CHAT_MSG_* event, and suppress the raw message from
appearing in chat.

This enables inter-addon communication used by:
- Boss mods (DBM, BigWigs) for timer/alert synchronization
- Raid tools (oRA3) for ready checks and cooldown tracking
- Group coordination addons for pull countdowns and assignments

Works with the existing SendAddonMessage/RegisterAddonMessagePrefix
functions that format outgoing messages as 'prefix\ttext'.
