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.

- Add FSR2 to ScalingFilter enum alongside existing FSR
- Implement FSR2 classes for both Vulkan and OpenGL renderers
- Add fsr2_quality_mode setting with 4 quality levels (Quality, Balanced, Performance, Ultra Performance)
- Integrate FSR2 into present pipeline for both renderers
- Add UI support for FSR2 option in scaling filter dropdown
- Add FSR2 quality mode setting with dropdown selection
- Update translations and Android strings for new options
- Default to Performance mode for optimal balance
This provides users with FSR 2.0 as a scaling option, offering different
quality/performance characteristics compared to FSR 1.0. The implementation
uses quality-based sharpening values and integrates seamlessly with the
existing rendering pipeline.

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

This patch enhances High DPI support across the Qt frontend with the following improvements:
**Windows DPI Awareness:**
- Add shellscalingapi.h include for Windows DPI functions
- 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.

- Fix memory leak in PopulateGridView() and FilterGridView() by properly
deleting old QStandardItemModel instances before creating new ones
- Add safety checks in controller navigation to prevent crashes when
accessing uninitialized controller data
- Improve controller input handling to only send events to visible and
properly initialized views
- Add null pointer checks in SetViewMode() to prevent crashes when
setting current index on empty models
- Add proper cleanup in GameList destructor to prevent memory leaks
on application shutdown
The main issue was that switching between list and grid views created
new models without properly cleaning up old ones, leading to memory
leaks. Additionally, controller navigation would send keyboard events
to both views simultaneously, causing crashes when one view was not
properly initialized or visible.
Fixes crashes when using controller navigation in grid view mode.
Thanks to Beta Testers acarajé & Hayate Yoshida (吉田 疾風) for finding the bug.

Add HasValueType concept to prevent compilation errors when using raw
pointers like const char* with Open() templates. The templates now only
participate in overload resolution for types that have a value_type
member (e.g., std::string, std::filesystem::path).

Fix multiple compilation errors preventing successful build:
* Add const qualifier to custom fmt formatter functions across codebase
- Updated formatters in logging, shader recompiler, texture cache, and other modules
- Ensures compatibility with newer fmt library versions
* Add missing fmt/ranges.h includes for fmt::join usage
- Fixed fmt::join calls in Vulkan renderer, GDB stub, NFC service, and main window
- Resolves "no member named 'join' in namespace 'fmt'" errors
* Exclude unsupported platforms from Boost.Process usage in debugger
- Extended conditional compilation to avoid Boost.Process where unavailable
* Fix type casting issues in AOC service manager
- Resolved std::min type mismatch with explicit casting
Add build system version detection as a fallback in GetCurrentVersion():
- Include common/scm_rev.h to access build version information
- Use Common::g_build_version when version.txt doesn't exist
- Automatically create version.txt with build version for future use
- Update comments to clarify version resolution priority
This ensures the updater can properly detect the current application
version even when version.txt hasn't been created yet, while maintaining
the existing priority system for version detection.

Replace direct file overwriting with a staging-based update mechanism to
resolve "file in use" errors during self-updates.
**Changes:**
- Stage updates to temporary directory instead of direct installation
- Apply staged updates on next application startup (before files are loaded)
- Add static methods for startup update detection and application
- Create update manifest to track staged update metadata
- Backup existing files before applying updates
- Update UI messaging to reflect staged update workflow
**Problem solved:**
The previous direct file replacement approach failed when trying to overwrite
DLLs and executables that were loaded into memory by the running process.
This two-stage approach stages files safely, then applies them on restart
when no files are in use.
**Workflow:**
1. Download and extract update to staging directory
2. Create manifest with update metadata
3. Show "Update ready" message to user
4. On next app startup: detect staged update, apply it, show success message
5. Clean up staging directory after successful application
This ensures reliable self-updates without file access conflicts.
