⭐feat(runner): Improve robustness and argument handling (#285)

## Description
Made argument parsing and handling much nicer with clap features.
Changed to tracing package for logging and made other improvements
around to hopefully make things more robust and logical.

Default audio-capture-method is now PipeWire since it seems to work
perfectly fine with latest gstreamer 🎉

## Summary by CodeRabbit

- **New Features**
- Improved command-line argument parsing with stricter validation, type
safety, and clearer help messages.
- Enhanced GPU selection and logging, including explicit GPU info
logging and support for negative GPU indices for auto-selection.
- Added support for new audio and video codec and encoder enums,
providing safer and more flexible codec handling.

- **Bug Fixes**
- Improved error handling and logging throughout the application,
unifying logs under the `tracing` system for better diagnostics.
- Fixed issues with directory ownership and environment variable
handling in startup scripts.

- **Refactor**
- Replaced string-based parsing and manual conversions with strongly
typed enums and value parsers.
- Updated logging from `println!` and `log` macros to the `tracing`
crate for consistency.
- Simplified and unified the handling of pipeline and element references
in the signaling and data channel logic.

- **Chores**
- Updated and cleaned up dependencies, including switching from `log` to
`tracing` and upgrading the `webrtc` crate.
- Removed unused or redundant code and environment variables for
improved maintainability.
