values in a dedicated table that can be referenced during rendering.
This implementation provides the foundation for zero-bandwidth clear
operations, allowing the GPU to efficiently clear color and depth
buffers using pre-defined values stored in the ZBC table.

- Replace stubbed QueryPointerBufferSize with comprehensive implementation
- Calculate pointer buffer size based on IPC message buffer requirements
- Account for all buffer descriptor types (X, A, B, W, C) and message headers
- Include proper alignment and overhead calculations
- Cap buffer size to reasonable maximum (64KB) to prevent excessive memory usage
- Use dynamic calculation instead of hardcoded 0x8000 value

This commit addresses serveral bugs within the audio service where OpenAL would fail to register the output device to the mapped engine.
- Increase null safety checks for all audio backends (cubeb, sdl2, openal)
- Added failsafe for Device selection
These ensure the audio_renderer can validate calls from the OpenAL engine, Credits to Hayate Yoshida for helping Identify the issue.

Fix LTO linking issues on CachyOS with GCC 15.x
- Add LTO support to all core library targets (input_common, frontend_common,
network, shader_recompiler, web_service) that were missing LTO configuration
- Create citron_configure_lto() helper function for consistent LTO handling
- Implement CachyOS-specific detection via /etc/os-release and kernel version
- Apply conservative LTO flags (-flto=auto -ffat-lto-objects) only for
CachyOS + GCC 15+ to resolve linking errors with newer toolchains
- Other distributions continue using aggressive LTO settings for maximum performance
- Disable LTO on executable targets to prevent main function optimization issues
This resolves "undefined symbol" errors when building with -DCITRON_ENABLE_LTO=ON
on CachyOS while maintaining optimal LTO performance on other distributions.
Fixes linking errors including:
- Core::Frontend::EmuWindow symbols
- Core::System methods
- Settings::values
- Common logging functions
Tested on CachyOS with GCC 15.1.1 + LLD 20.1.8

- Implement Per Monitor DPI Awareness (Windows 8.1+) and Per Monitor v2 DPI Awareness (Windows 10+)
- Use SetProcessDPIAware() and SetProcessDpiAwareness() for better multi-monitor scaling
- Dynamically load shcore.dll to access modern DPI awareness APIs
**Configuration Dialog Enhancements:**
- Add comprehensive High DPI responsive CSS media queries for different DPI levels (192dpi, 240dpi)
- Scale UI elements (buttons, comboboxes, line edits, checkboxes, radio buttons) based on screen DPI
- Improve scroll area styling with proper scrollbar theming for high DPI displays
- Set proper window attributes for scaling (WA_TranslucentBackground, WA_NoSystemBackground)
- Calculate logical window size based on device pixel ratio for accurate scaling
**UI Improvements:**
- Enhanced scroll area styling with custom scrollbar appearance
- Better visual feedback with hover effects on scrollbar handles
- Improved spacing and sizing for high DPI displays
- Set proper window modality and title for configuration dialog
These changes provide better visual quality and usability on high DPI displays, particularly on Windows systems with multiple monitors or high-resolution screens. The scaling is now more accurate and consistent across different display configurations.
