- Moved the copy buffer to the heap via std::make_unique.
- Added explicit null-safety and system shutdown checks to mirroring logic.
- Hardened recursion guards during directory traversal to ensure stability.

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.

Remove the 'reliable' boolean field from LDNPacket and ProxyPacket
structs and all associated serialization/deserialization logic.
All packets now use reliable delivery by default via ENet layer,
matching the legacy format for full backward compatibility.

- Add size validation before memcpy for Connect/Disconnect packets
- Allow empty data for Scan packets (Type 0) which have no payload
- Add debug logging for ScanResp packets including BSSID and results
- Fix MacAddress indexing to use .raw[] instead of [] operator

Handle error 2359-2618 (module 359, description 2618) gracefully
by logging a warning instead of crashing, similar to module 56.
This allows games like SSBU to continue execution when encountering
this error code.

- Add error checking after decompression to drop corrupted packets
- Add error checking after compression to prevent sending empty packets
- Allow ZSTD_CONTENTSIZE_UNKNOWN and use streaming decompression
- Only reject ZSTD_CONTENTSIZE_ERROR as a fatal error
Fixes network connectivity issues where corrupted/empty packets were
being processed, breaking the network protocol.

Fix crash in PinHandle when SMMU allocation fails and unmap queue is empty.
Previously, the code would log an error and continue looping indefinitely,
causing log spam and eventual crash.
- Free multiple handles from unmap queue (up to 100) before giving up
- Add maximum attempt counter to prevent infinite loops
- Return 0 gracefully when no more handles can be freed
- Add error handling in callers (Remap, MapBufferEx, MapBuffer) to check for
PinHandle failure and return NvResult::InsufficientMemory instead of using
invalid addresses

Fix crash in PinHandle when SMMU allocation fails and unmap queue is empty.
Previously, the code would log an error and continue looping indefinitely,
causing log spam and eventual crash. Now it returns 0 to fail gracefully.
Also fix incorrect handle check on line 219 - should check freeHandleDesc
instead of handle_description.

Fixes crashes in Minecraft and other games when encountering unsupported
socket operations or attempting to use Nintendo's online services.

The TitleID check was broken due to using || operator which evaluated
to 1 instead of a title ID value, preventing the recovery mechanism
from working.
- Fix title_ids.h: Replace incorrect || expression with proper
LittleNightmares3Base constant (0x010066101A55A000)
- Update physical_core.cpp: Use GetBaseTitleID() to match both
base and update title ID variants
This now correctly identifies Little Nightmares 3 and enables the
recovery mechanism that sets PC to LR when detecting null pointer
execution loops.

The PC < 0x1000 recovery mechanism introduced in commit fbb4f5c0
was causing issues for other games. This change restricts the recovery
to only apply when the title ID matches Little Nightmares 3.
- Add LittleNightmares3 title ID constant to title_ids.h
- Check program ID before applying PC return recovery in physical_core.cpp
- Recovery now only triggers for Little Nightmares 3 (010066101A55A800)
to avoid affecting other games
Fixes issues caused by the general PC return recovery in other titles.

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.
