test-build: add --local-deps for in-repo deps

Resolve deps that are siblings in the target's own repo (not on SBo or
official Slackware) by prepending the target's repo root to the dep search
roots when --local-deps is passed. The SBo tree is still searched after.

Covers packages like huggingface_cli whose deps live in the same
maintenance repo. Adds two logic self-checks and updates CLAUDE.md,
README, and the test-build-slackbuild skill.
