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.

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.

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.
