fix(install): use glslc with glslang-tools fallback for Vulkan shader support

Browse Source 
- Try glslc first (available on Ubuntu 24.04+)
- Fall back to glslang-tools if glslc not available (Ubuntu 22.04)
- Update user-facing messages to mention both packages
- Fixes #212 while maintaining compatibility with newer Ubuntu versions
