daemon: build a work-seed during image pull, refresh doctor check
Before this change `banger image pull` (both OCI-direct and bundle
paths) shipped images with an empty WorkSeedPath — the BuildWorkSeedImage
helper existed only behind the hidden `banger internal work-seed` CLI.
Every pulled image hit ensureWorkDisk's no-seed branch, and the guest
booted with a bare /root (no .bashrc, no .profile, none of the distro
defaults).

Pull now calls BuildWorkSeedImage after the rootfs is finalised (OCI)
or fetched (bundle). The builder is behind a new `workSeedBuilder` test
seam so existing pull tests don't accidentally demand sudo mount. The
build failure is non-fatal: any error logs a warning and leaves
WorkSeedPath empty — images stay publishable even if the pulled rootfs
has no /root to extract.

Verified end-to-end by wiping the cached smoke image and re-pulling:
work-seed.ext4 lands in the artifact dir next to rootfs.ext4, and all
21 smoke scenarios pass.

Also refreshes the "feature /root work disk" fallback tooling check —
the no-seed path no longer touches mount/umount/cp after commit
0e28504, so the doctor check now only requires truncate + mkfs.ext4.
The warn copy updates from "new VM creates will be slower" to "guest
/root will be empty", which matches the actual tradeoff post-refactor.
