Update dependencies and improve CLI argument handling

- Updated various dependencies in Cargo.toml and Cargo.lock, including `env_logger`, `fs-err`, and `clap`, to their latest versions for enhanced functionality and security.
- Refactored CLI argument handling in `build.rs` and `mod.rs` to align with the new `clap` version, improving error reporting and verbosity options.
- Added new packages such as `anstream`, `colorchoice`, and `jiff` to enhance project capabilities.
