…me CDP bind
ensurePortAvailable used bare net.listen({port}) which binds IPv6
wildcard on dual-stack, missing IPv4-only loopback occupants.
This caused Chrome CDP launch to fail with misleading HTTP 401
when 127.0.0.1:<port> was already in use.
Probe 127.0.0.1 explicitly to match the address family Chrome
binds its debugging port on.

Summary
Fixes #94379
ensurePortAvailable()used barenet.listen({port})which binds the IPv6 wildcard on dual-stack hosts, missing IPv4-only loopback occupants. Chrome CDP binds on127.0.0.1, so the pre-flight guard was silently bypassed. Chrome then fails withbind() failed: Address already in usebut the user sees a misleadingHTTP 401.Root Cause
The address family the pre-flight probes (
::) does not match the address family Chrome binds (127.0.0.1). An IPv4-only occupant goes undetected.Change
src/infra/ports.ts— 1 lineProbe
127.0.0.1explicitly to match Chrome's CDP bind address family. The siblingcheckPortInUsealready probes all 4 loopback families — this alignsensurePortAvailablewith that pattern.Testing
pnpm not available in local environment — relying on CI verification.
