Add hermes-enhancement/: pi-style behavioral enhancement for Hermes agents

Self-service enhancement package for Hermes agents to adopt pi-style
conduct quality. Contains:
- prompts/behavioral-core.md: Distilled Three Pillars (~800 tokens)
- config/compression.yaml: 256K model optimization (80% threshold)
- config/mcp-servers.yaml: Tool parity (Context7, GitHub, Firecrawl, etc.)
- skills/: On-demand skills for conduct, verification, self-healing
- CHECKLIST-POC.md: Tanko POC verification checklist
