This commit implements Phase 3b/3c architectural improvements:
### New kugetsu CLI commands:
- `kugetsu status` - Check initialization status (replaces kugetsu-helper check-status)
- `kugetsu delegate <msg>` - Send message to PM agent (new command)
- `kugetsu doctor [--fix]` - Diagnose and fix kugetsu issues
### PM Context Injection:
- kugetsu init now reads ~/.kugetsu/pm-agent.md (if exists) and injects
it into the PM agent session at creation time
- PM context is loaded ONCE at init, not on every delegation
- This improves efficiency - kugetsu-pm content read once, not 10 times
### kugetsu-chat updated:
- Now uses `kugetsu delegate` instead of kugetsu-helper
- Now uses `kugetsu status` instead of kugetsu-helper check-status
- Simplified - no longer depends on kugetsu-helpers
### kugetsu continue:
- Removed strict issue-ref format validation
- Now accepts any session name that is tracked in index.json["issues"]
- Issue-ref format is a guideline, not a hard requirement
### Documentation updated:
- phase3a-setup.md - Updated to reflect new kugetsu commands
- kugetsu-install.sh - Simplified Phase 3a setup instructions
### Breaking changes:
- kugetsu-helpers is no longer required for Phase 3a Chat Agent
- kugetsu-chat skill v3.0 now requires kugetsu CLI with new commands
- SKILL.md: More explicit about MUST use this skill for delegation
- SOUL.md: Explicitly instruct to invoke /kugetsu-chat skill first
- Add more explicit delegation rules and error handling
- SOUL.md: only personality/voice guidance (no routing logic)
- SKILL.md: definitive routing behavior + delegation process
- Add context passing via temp file for long tasks
- Add error handling table with user-friendly messages
This aligns with Hermes docs: SOUL.md = identity, SKILL.md = behavior
