chore(orchestrator): Bootstrap MS23 mission-control tasks.md + PRD

29 tasks across 5 phases.
Gitea issues: #693 (P0), #694 (P1), #695 (P2), #696 (P3), #697 (P4).
Milestone: 0.0.23
Estimated total: ~478K tokens.

Phase order:
  P0: Backend core (message storage, SSE streaming, barge-in, subagent tree)
  P1: IAgentProvider interface + registry + proxy API
  P2: Mission Control UI (panels, roster, audit log, kill-all)
  P3: OpenClaw external provider adapter
  P4: QA, security review, deploy, v0.0.23 release
