Implement interrupt handling for long-running commands and archive extraction

- Added an `interrupts` module to manage Ctrl-C signals and propagate them to child processes.
- Refactored archive extraction functions to check for interrupts and handle them gracefully.
- Introduced `copy_interruptibly` function to allow for interruptible copying of data.
- Updated various source files to utilize the new interrupt handling functions, ensuring that commands and archive extractions can be interrupted by the user.
- Added tests to verify the interrupt functionality during copying and tar extraction.
- Introduced a new Meson option for generating HTML CLI documentation.
- Enhanced the `PackageSpec` struct to support additional Rust LTO flags.
