Remove proxy listener and integrate DA-style networking transport

[wren11]

What changed

• removed the local TCP proxy listener model from WrenLib/Proxy.cs and replaced it with a DA-inspired in-process transport manager
• preserved the existing NewProxy / ProxySocket event API (OnConnect, OnRecv, OnSend, OnDisconnect, etc.) so WrenBot handlers and scripts keep working without broad refactors
• implemented DA-style packet send operation in ProxySocket.SendPacketTransformed by reading SEND_THIS and invoking FUNC_SEND via remote shellcode injection
• moved connection discovery to process polling for Darkages clients instead of local socket accept/listen

DA reference alignment

Integrated concepts from https://github.com/wren11/da/tree/main:

• fixed game addresses (SEND_THIS, FUNC_SEND) and packet operation invocation pattern (PacketOperation.cpp)
• process-attached transport mindset (hook/in-process client instead of local proxy server)

Notes

• no local server bind/listen occurs anymore (proxy server removed)
• Linux/cloud builds still succeed; Windows-only injection path is guarded to avoid runtime failure on non-Windows hosts

Validation

• xbuild WrenBot.sln /p:Configuration=Debug succeeds
• app starts successfully after this change and remains responsive
• walkthrough artifacts:
  • wrenbot_da_networking_demo.mp4
  • WrenBot running after DA transport integration
  • WrenBot responsive interaction after DA transport integration
  • wrenbot_da_networking_runtime.log
