feat: ArcheFlow — multi-agent orchestration plugin for Claude Code

Zero-dependency Claude Code plugin using Jungian archetypes as
behavioral protocols for multi-agent orchestration.

- 7 archetypes (Explorer, Creator, Maker, Guardian, Skeptic, Trickster, Sage)
- ArcheHelix: rising PDCA quality spiral with feedback loops
- Shadow detection: automatic dysfunction recognition and correction
- 3 built-in workflows (fast, standard, thorough)
- Autonomous mode: unattended overnight sessions with full visibility
- Custom archetypes and workflows via markdown/YAML
- SessionStart hook for automatic bootstrap
- Examples for feature implementation and security review
