Greptile Summary

Adds codereviewbuddy check-env CLI command for validating configuration before starting the server. Built on cyclopts framework, this provides a diagnostic tool that lists all CRB_* environment variables (masking sensitive values), validates their types and constraints via load_config(), detects typos in unrecognized vars, and checks gh CLI authentication status.

Key changes:

• New cli.py module with cyclopts app structure: serve as default command and check-env for diagnostics
• Entry point changed from server:main to cli:app in pyproject.toml
• main() removed from server.py (functionality moved to cli.serve())
• Sensitive value masking shows first/last 2 chars for values >4 chars, full mask for shorter values
• 11 new test cases with good edge case coverage
• Proper T201 linter exception added for CLI print statements

Confidence Score: 5/5

• Safe to merge - well-structured refactor with comprehensive tests and clear separation of concerns
• Clean implementation with proper error handling, comprehensive test coverage (11 new tests covering edge cases), sensible defaults, and no breaking changes to existing functionality. The masking logic is secure, the refactoring is minimal and focused, and all integration points are properly tested
• No files require special attention
