🐜 fix(runner): Improve NVIDIA driver handling, switch to gamescope (#279)

## Description
- Made it so failed NVIDIA driver install won't quit entrypoint script
if other GPU vendors are present (fixes mixed GPU cases).
- Switch to gamescope as compositor, with optional SYS_NICE cap handling
for higher priority.
- Use mangohud preset 2 for stats, which is more compact.
- Fixes to nestri-server lspci regex, to deal with AMD naming scheme.
- Added missing radeon vulkan driver packages.

systems without NVIDIA GPUs.
	- Enhanced PCI device parsing for more accurate GPU detection.

- **Chores**
- Updated environment configuration to use X11 session type and set
MangoHud preset.
- Removed unused packages and legacy compositor/resolution management
logic.
