docs: add comprehensive project context for future Claude sessions

- Add detailed project overview and architecture documentation
- Document key design decisions and implementation details
- Include test suite information and development workflows

- Add project status summary showing completion of all requirements

This context will help future Claude instances understand the project
structure, architecture, and current state without needing to re-analyze
the entire codebase.
