ORGANIZE: Move documentation to proper directories

- Moved API design docs to docs/api-design/
- Moved planning docs to docs/planning/
- Root now only contains standard repo files (README, LICENSE, etc.)
- Keeps CLAUDE.md and PLAN.md uncommitted for privacy

Clean root directory for better project organization.
