Mission Run: Event Architecture: Git Semantic Truth + WebSocket Awareness (CLI)

Establish git as the durable record for decision events, add real-time local-commit WebSocket notifications, strip PII from all event envelopes, and reduce glossary queue noise.

The current CLI event system routes decision events only through a SQLite queue, embeds PII in event envelopes, has no way to notify the SaaS of local commits before a push, and floods the queue with per-extraction glossary noise. This mission fixes all four issues: decision events become durable git commits, a new LocalCommit WebSocket frame gives the SaaS real-time build-surface awareness, a sanitizer removes PII at the write boundary, and the glossary queue is trimmed to only semantically meaningful human decisions.
