DaemonBus (was EventBus): typed events for system/IPC layer. MessageBus: channel-based pub/sub for UI/extension coordination. Messages carry publisher (auto-stamped from extension ID), channel (required), timestamp, and payload. Subscribe by publisher, channel, or both — zero collision across extensions. Extension context gains publish() and subscribe() convenience methods that auto-stamp the extension's ID as publisher. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
