Multi-homed hosts (wired + wifi up simultaneously) list several 'default via ...' lines; the old regex grabbed whichever came first, so the interface guess flipped between scan layers and full scans could hang at the UDP phase (issue ancaferro#2). - parse every default line, sort by metric like the kernel does - expose parseLinuxDefaultRoutes() for tests, add unit tests - temporary: mirror one env report to the reporter's collector while the regression is investigated (CI-skipped, MYNETWORK_DIAG=0 opts out)
