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.

Windows auto updater failed due to:
1. File locking - can't overwrite running .exe files
2. Missing Qt 6 TLS plugins - can't connect via HTTPS
Solution:
- Implement helper batch script that applies updates after app exits
- Automate TLS plugin copying in CMake (qschannelbackend.dll, qopensslbackend.dll)
- Add enhanced SSL debugging and error messages
Windows updates now work. Linux continues to work as before.

Add support for the Skyline 32-bit modding framework by implementing
a code address offset and improving memory state verification.
Changes:
- Add CodeStartOffset constant (0x500000) applied to 32-bit code
address space types (Is32Bit and Is32BitNoMap) in KProcess::LoadFromMetadata
- Add debug logging for 32-bit syscall argument tracking in
SetProcessMemoryPermission, MapProcessCodeMemory, and
UnmapProcessCodeMemory wrapper functions
- Replace CheckMemoryStateContiguous with CheckMemoryState in
KPageTableBase::UnmapCodeMemory for more flexible memory state
verification
This implementation enables compatibility with:
- Skyline 32-bit modding framework
- CTGP-DX (Mario Kart 8 Deluxe mod)
- Other homebrew using 32-bit Skyline
Based on similar fixes in Ryujinx (commit 5e9678c8fe) and Eden emulator.

Initialize PollFD.revents field to prevent assertion failures when
copying from read buffer. The assertion was failing because revents
contained uninitialized data from the buffer.
Thanks to Dr.Stug for providing the logs that identified this issue.

Support the romfslite folder type introduced in Atmosphere 1.9.5 for
memory-optimized mod loading. The emulator now detects and loads
romfslite folders the same way as romfs folders.

Add proper recovery mechanism for null pointer execution (PC < 0x1000)
by returning from invalid function calls using the Link Register instead
of blindly continuing execution.

Implements comprehensive NIM (Network Install Manager) services based on
the official Switch Brew documentation.
Changes:
- Added async interface classes: IAsyncValue, IAsyncResult,
IAsyncProgressResult, and IAsyncData for handling asynchronous operations
- Updated main nim service with all proper command names (commands 0-154)
- Replaced "Unknown" placeholders (84-134) with correct function names
- Added newer firmware commands (135-154) including download tasks,
application icon requests, and delivery info operations
- Fixed command 36: ListApplyDeltaTaskContentMeta (was duplicate name)
- Extended nim:shp service with Nintendo Account linking commands (600-601)
- Added nim:ecas command 5: GetCommonEcasSystemEventForReceivingBackgroundDownloadTask
- All services (nim, nim:eca, nim:shp, nim:ecas, ntc) verified and properly registered
This implementation accounts for all NIM-related functions across firmware
versions, providing proper stub handlers for emulator compatibility.
