Resolve pm2 ports from listening sockets instead of env vars

[fredrivett]

Port detection previously read the bare PORT or any *_PORT env var from pm2_env, which inside Conductor latched onto the inherited CONDUCTOR_PORT allocation — overriding an app's real port and giving non-server processes a phantom one. This replaces the heuristic with SocketScanner, which resolves each process's ports from the actual listening sockets (one lsof + one ps per refresh, machine-wide) and attributes ports opened by child processes too, so npm-wrapped servers (pm2 start npm -- run dev) resolve correctly. PM2Process.port (Int?) becomes ports ([Int]): the row shows up to two ports as links with a +N overflow badge and a tooltip listing all, while the env header keeps its band/range aggregated over the real ports. The decoder no longer enumerates pm2_env at all, IPv4/IPv6 bindings collapse, and debug/inspector ports (9229–9231) are filtered. Adds a pure PortDisplay helper and tests covering socket parsing, process-tree resolution, debug filtering, and the display logic.

Summary by cubic

Resolve PM2 ports from actual listening sockets instead of env vars to prevent phantom ports and correctly attribute child process listeners; the UI now shows up to two ports with a +N overflow and the env header aggregates real port ranges.

• Bug Fixes

  • Stop reading PORT/*_PORT from pm2_env; use SocketScanner (one lsof + one ps per refresh) to map ports by pid and descendants. Fixes CONDUCTOR_PORT bleed-through and npm-wrapped servers.
  • Collapse IPv4/IPv6 duplicates and filter debug ports 9229–9231.

• Refactors

  • Replace PM2Process.port with ports: [Int]; update search, env header band/range, and rows via ProcessPortsView (shows up to two ports with a +N tooltip).
  • Add pure PortDisplay helper and tests for socket parsing, process-tree resolution, debug filtering, and display logic; decoder no longer enumerates pm2_env.
