Modernize Rust codebase: Fix chrono deprecations and enhance development tools (#415)

- Fix chrono deprecation warnings by updating to modern APIs
- Add comprehensive clippy configuration for stricter linting
- Enhance Makefile with development targets (check, clippy, fmt, test, clean, help)
- The Cargo.toml already had Rust 2024 edition and modern clippy lints configured
