- Add agents/agent-coach.md: new meta-category coaching agent that reads
all project agent memories, synthesises cross-agent briefs, and produces
targeted orientation briefs for incoming agents
- Complete memory brief command: now reads all .kaizen/agents/*/memory.md,
formats structured orientation output following coach agent spec, adds
--raw flag for unformatted dump
- Coach validates and appears under kaizen-agentic list --category meta
