AI Summary

This update extends wire protocol v2 support to UDP-based proxy payloads and improves SUDP compatibility during mixed protocol deployments.

Key Highlights

Wire protocol v2 now applies to UDP-based proxy payloads (ordinary UDP and SUDP).
Improved SUDP compatibility when bridging payloads between v1 and v2 clients.
XTCP work connection NatHoleSid messages now follow the selected wire protocol.

Breaking Changes

Enabling `transport.wireProtocol = "v2"` for SUDP requires upgrading both the proxy and visitor instances to avoid compatibility issues.

New Features

Wire protocol v2 application to UDP payloads
Enhanced SUDP compatibility in mixed deployments

Full Release Notes

## Features

* `transport.wireProtocol = "v2"` now also applies to UDP-based proxy payloads, including ordinary UDP and SUDP, so their payload framing is consistent with the selected wire protocol.
* Improved SUDP compatibility during mixed `transport.wireProtocol` deployments, allowing frps to bridge payloads between v1/default and v2 SUDP clients.
* XTCP work connection `NatHoleSid` messages now follow the selected `transport.wireProtocol`.

## Compatibility Notes

* When enabling `transport.wireProtocol = "v2"` for SUDP, upgrade both the proxy and visitor frpc instances first, or keep them on `v1` until both sides are upgraded.
