feat: add more socket features

[maschad]

Summary by CodeRabbit

• New Features

  • Added comprehensive socket monitoring and analysis capabilities, including real-time tracking of socket events and detailed reporting of TCP/UDP socket statistics.
  • Introduced advanced TCP connection metrics such as congestion control, round-trip time, retransmits, packet loss, buffer bloat detection, and connection quality scoring.
  • Enhanced socket metadata with new fields for socket type, family, flags, and options.
  • Added examples demonstrating socket information retrieval and analysis.
  • Integrated new libraries to improve socket data retrieval on macOS and Linux, replacing command-line tools with direct system calls for better performance and reliability.

• Documentation

  • Added detailed documentation on socket information integration and usage, including platform-specific behaviors, limitations, and future improvement plans.

Walkthrough

This update introduces comprehensive enhancements to socket information gathering, analysis, and reporting across platforms. It adds new dependencies (libproc, optionally procfs), expands socket metadata and TCP statistics, and provides new example programs. Documentation details the integration of libproc and platform-specific implementations. The codebase now supports richer connection health analysis and reporting.

Changes

File(s)	Change Summary
Cargo.toml	Added libproc and optional procfs dependencies; introduced linux-procfs feature; registered new example socket_info_libproc.
SOCKET_LIBPROC_INTEGRATION.md	Added documentation explaining libproc integration, platform-specific strategies, available socket info, limitations, and future improvements.
examples/socket_analysis.rs	New example: real-time socket monitoring and detailed analysis using SocketMonitor and helper functions for statistics and connection health.
examples/socket_info_libproc.rs	New example: retrieves and displays comprehensive socket info (TCP/UDP) using the libproc interface, including TCP stats and performance analysis.
src/socket/monitor.rs	Enhanced SocketInfo creation in event handling: sets socket_type, socket_family, socket_flags, and socket_options based on protocol.
src/socket/platform.rs	Major expansion: SocketStats gains many TCP/congestion/quality fields and analysis methods; SocketInfo gains type/family/flag/option fields; platform modules improved for richer, cross-platform data gathering and health analysis.
src/socket/tcp.rs, src/socket/udp.rs	SocketInfo conversion implementations now set socket_family, socket_type, socket_flags, and socket_options for TCP and UDP sockets.

Poem

In the warren of code, new tunnels appear,
With libproc and procfs bringing sockets near.
Now rabbits can sniff every TCP hop,
Congestion, bloat, and stats that won't stop!
From burrow to byte, connection health in view—
Hopping through sockets, with metrics anew!
