docs: Add multi-session/LLM continuity references

- Update README.md to prioritize PROJECT_STATE.md for new agents
- Add handoff instructions to implementation plan header
- Ensure any agent/LLM knows to check current status first
- Create clear documentation hierarchy for handoffs
- Fix markdown formatting issues

This ensures any AI agent or human developer can immediately
understand project state and continue work without confusion.
