Add CRT (Cathode Ray Tube) shader implementation as scaling filter
options (CRT EasyMode and CRT Royale) in the Window Adapting Filter
dropdown. Provides classic TV effects including scanlines, phosphor
masks, curvature distortion, gamma correction, bloom, brightness, and
alpha transparency.
- Add CRTEasyMode and CRTRoyale to ScalingFilter enum
- Implement vulkan_crt_easymode.frag shader with single-pass effects
- Integrate CRT filter into WindowAdaptPass rendering pipeline
- Add configurable CRT parameters to settings with user-friendly labels
- Add UI translations for desktop and Android platforms
- Support CRT push constants in present pipeline
The CRT filter appears alongside other scaling filters like FSR and
FSR 2.0. CRT parameter settings are only active when a CRT filter
is selected.

Added a "Global Custom Save Path" configuration option in the Filesystem settings.
Implemented a prioritized save-loading hierarchy: Global Path (if enabled) > Per-Game Custom Path > Default NAND.
Introduced a non-destructive migration tool that allows users to consolidate their existing saves into the new global location.
The migration tool specifically prioritizes per-game custom saves over NAND saves to ensure the most up-to-date data is preserved during consolidation.
The migration process is copy-only; no data is deleted from the source directories, ensuring absolute user data safety.
Maintained compatibility with the existing "Backup Saves to NAND" feature, ensuring saves continue to be mirrored internally if configured.

Major networking enhancements to improve multiplayer performance and
reduce desync issues in games like Mario Kart 8 Deluxe:
Network Performance:
- Add socket connection pooling in BSD service to reduce overhead
- Implement unreliable packet delivery for latency-sensitive game data
- Add packet reliability control for both ProxyPacket and LDNPacket
- Use ENET_PACKET_FLAG_UNSEQUENCED for small UDP packets (<1200 bytes)
Monitoring & Debugging:
- Add PacketStatistics struct to track sent/received/dropped packets
- Enhanced logging for proxy packet handling and socket lifecycle
- Periodic stats logging every 100 packets for diagnostics
Configuration:
- Update lobby_api_url and web_api_url to https://api.ynet-fun.xyz
- Add lobby API URL configuration support
Socket Management:
- Implement SocketPoolKey for efficient socket reuse
- Store domain/type/protocol info in FileDescriptor
- Max pool size limit (8 sockets per type) to prevent memory bloat
- Return closed sockets to pool when room is still connected
Protocol Updates:
- Add 'reliable' field to ProxyPacket and LDNPacket structures
- Update room.cpp packet handlers to respect reliability flags
- Maintain backward compatibility with default reliable=true
These changes significantly reduce packet latency for real-time game
traffic while maintaining reliability for control packets.

Adds user option to disable Vulkan conditional rendering, which can fix
flickering objects in some games caused by rapidly toggled draw calls.
Changes:
- Add use_conditional_rendering setting (default: enabled)
- Guard conditional rendering functions with setting check using [[unlikely]]
- Early exit in Pause/Resume and Compare functions when disabled
Disabling this in Graphics (Advanced) fixes flickering at cost of performance.

Benefits:
- Improved type safety and compiler error messages
- Better IDE support for navigation and refactoring
- More explicit and self-documenting code
- Easier to debug enum-related issues

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
