Merge claude/2

The rootless dockerd override forced NET=pasta + PORT_DRIVER=builtin, which
rootlesskit rejects ('pasta requires port driver none or implicit'), so the
daemon failed to start every time (the real cause behind 'rootless socket not
found'). Use slirp4netns + builtin (valid, still skips the userspace
port-handler). Verified: daemon now comes up, docker Server 29.5.2 responds.
