"""Make the CAD skill (skill.src/modules/*) importable.

skill.src uses package-relative imports under a top-level `modules` package, the
same way step_processor.py runs it (script dir on sys.path[0]). We replicate that
by putting SKILL_SRC on sys.path, then `import modules.loader` etc. resolves.

Heavy deps (build123d/OCP) are imported lazily inside the skill functions, so
importing the modules here is cheap; the kernel only loads when a job runs.
