* fix(ports): validate lsof PID parsing before assignment

Add Number.isFinite guard on lsof 'p' line PID parsing in
parseLsofOutput, consistent with the netstat branch in the same
function which already validates with Number.isNaN.

While the downstream if (current.pid) truthiness check catches
NaN (falsy), adding validation at the parse site is defense-in-
depth and eliminates an inconsistency within the same function.

* test(ports): add edge case tests for parseLsofOutput

Add test coverage for malformed lsof 'p' lines (empty PID, non-numeric
suffix), zero PID, and empty input to verify the Number.isFinite guard
correctly filters invalid entries.
