[feature]: extended TCP stats in details view

[Worty]

Problem / Use Case

Hi, have you ever thought about adding more TCP stats to the details view, like ss -i -t does?

ESTAB                                    0                                         0                                                                            [2a02:aaaa:bba:cccc::1]:35290                                                                           [2001:dddd:dddd:4::1]:imaps
         cubic wscale:7,10 rto:229 rtt:28.311/7.017 ato:40 mss:1428 pmtu:1500 rcvmss:1428 advmss:1428 cwnd:10 bytes_sent:13820 bytes_acked:13821 bytes_received:33477 segs_out:521 segs_in:406 data_segs_out:296 data_segs_in:350 send 4.04Mbps lastsnd:112832 lastrcv:112804 lastack:12320 pacing_rate 8.07Mbps delivery_rate 860kbps delivered:297 app_limited busy:9124ms rcv_space:14280 rcv_ssthresh:91993 minrtt:16.201 snd_wnd:64128 rcv_wnd:92160

Unfortunately these informations are not available via /proc/net/tcp, but only via netlinks INET_DIAG_INFO. I have no clue how these things works on macOS.

Proposed Solution

I vibe coded a implementation which works fine for me at https://github.com/Worty/snitch/tree/tcp-details , but wanted to ask if you like the idea before I put more effort in it for a PR.

There are some other interesting fields, such as app_limited busy, send/receive windows (scale) and pmtu, but I haven't added them yet.

If you want, I can open a draft PR.

this is a really cool idea, would love to see a draft pr. keep in mind macos support (even if stubbed) and keeping the detail view clean since there are a lot of possible fields. happy to also iterate on it in the pr

just please really try to really understand the llm code and avoid like the usual issues
