What it does

• Every TCP listener → PID → executable → owning project (walks up to package.json / pom.xml / go.mod / .git)
• devcheck why 5000 → "that's AirPlay Receiver, turn it off or use 5001"
• Duplicate listeners, fake-alive listeners (listening but no TCP handshake), runaway CPU
• GUI app / system daemon noise hidden by default
• Menu bar: open in browser / copy address / reveal in Finder / SIGTERM
• Zero dependencies, zero privileges, no network I/O; bilingual (en/zh)
