fix(ssh-tunnel): pass host to ensurePortAvailable in startSshPortForward

zhangqueping · zhangqueping · commit dd44ca005a83 · 2026-06-19T23:14:06.000+08:00
- ensurePortAvailable was called without the host parameter, defaulting to "localhost" which can miss IPv4-only occupants on dual-stack hosts - Pass parsed.host to ensurePortAvailable to match the expected address family for port availability checks Fixes #94596
