extract docker tooling to ../sbo-dockerbuild

The test-build tool and image-builder chain grew from a .extras/ helper into a
standalone toolchain, now maintained in its own repo (../sbo-dockerbuild). Remove
them here (scripts, examples, design docs) and repoint CLAUDE.md: test-building
is now done with the installed `test-build` CLI, deps resolved from the SBo tree,
both trees verified per bump. Package-maintenance files stay: nvchecker.toml,
hooks/, assets/.
