Project State Management：用事件化状态替代静态看板

• State file schema is defined with event types, owner, timestamp, and status fields.
• All collaborators agree on append-only event logging rules.

1. Initialize per-project state file and seed with baseline milestone events.
2. Require each agent/task to append start/update/finish events.
3. Generate human-readable summaries from event stream at fixed checkpoints.
4. Archive closed projects while preserving immutable state history.

• Inconsistent event naming will break downstream summaries and automation.
• Schema evolution/migration policy must be versioned（需验证）.
