Code Quality Improvements:
- Fix hex literal grouping in ID generator (0xB10C_1D -> 0x00B1_0C1D)
- Rename ListQuery::default() to default_query() to avoid confusion with Default trait
- Use div_ceil() instead of manual ceiling division
- Remove unnecessary borrows in auth token generation and hashing
- Simplify nested if statements in error handling
Documentation:
- Add comprehensive authentication section to README
- Document environment variables for server and CLI
- Add security best practices and considerations
- Document password hashing (Argon2id), token storage (SHA-256), and session management
- Include step-by-step authentication setup guide
- Add production deployment recommendations
All 70 tests pass (8 unit + 46 server + 16 CLI) ✅
