⭐ feat(runner): More runner improvements (#294)

## Description
Whew..

- Steam can now run without namespaces using live-patcher (because
Docker..)
- Improved NVIDIA GPU selection and handling
- Pipeline tests for GPU picking logic
- Optimizations and cleanup all around
- SSH (by default disabled) for easier instance debugging.
- CachyOS' Proton because that works without namespaces (couldn't figure
out how to enable automatically in Steam yet..)
- Package updates and partial removal of futures (libp2p is going to
switch to Tokio in next release hopefully)

## Summary by CodeRabbit

- **New Features**
- SSH server can now be enabled within the container for remote access
when configured.
- Added persistent live patching for Steam runtime entrypoints to
improve compatibility with namespace-less applications.
- Enhanced GPU selection with multi-GPU support and PCI bus ID matching
for improved hardware compatibility.
- Improved encoder selection by runtime testing of video encoders for
better reliability.
  - Added WebSocket transport support in peer-to-peer networking.
- Added flexible compositor and application launching with configurable
commands and improved socket handling.

- **Bug Fixes**
- Addressed NVIDIA-specific GStreamer issues by setting new environment
variables.
  - Improved error handling and logging for GPU and encoder selection.
- Fixed process monitoring to handle patcher restarts and added cleanup
logic.
- Added GStreamer cache clearing workaround for Wayland socket failures.

- **Improvements**
- Real-time logging of container processes to standard output and error
for easier monitoring.
- Enhanced process management and reduced CPU usage in protocol handling
loops.
- Updated dependency versions for greater stability and feature support.
  - Improved audio capture defaults and expanded audio pipeline support.
- Enhanced video pipeline setup with conditional handling for different
encoder APIs and DMA-BUF support.
- Refined concurrency and lifecycle management in protocol messaging for
increased robustness.
- Consistent namespace usage and updated crate references across the
codebase.
- Enhanced SSH configuration with key management, port customization,
and startup verification.
  - Improved GPU and video encoder integration in pipeline construction.
- Simplified error handling and consolidated write operations in
protocol streams.
- Removed Ludusavi installation from container image and updated package
installations.

- **Other**
- Minor formatting and style changes for better code readability and
maintainability.
- Docker build context now ignores `.idea` directory to streamline
builds.
