Capture TCP and UDP traffic

Description

Add native support for capturing and inspecting raw TCP and UDP traffic in Proxyman, as an optional “Socket Capture” mode. This would present all TCP and UDP packets in the familiar Proxyman UI, with process-based grouping, live filtering, and protocol-specific inspectors.

Why this feature/change is important?

This would be game-changing for a lot of people, it would provide a one-stop diagnostic tool for both high and low-level network analysis.
Today, developers must juggle Proxyman for HTTP/S and Wireshark (or tcpdump) for TCP/UDP, each with different UIs, steep learning curves, and no seamless hand-off.
Proxyman’s per-app traffic separation extended to TCP/UDP means you can instantly correlate, say, an IoT device’s MQTT packets or a game’s UDP voice-chat with the originating app, without deciphering random port numbers.
