[Change] Codebase import runtime hardening #235

Summary

specfact code import currently scans hidden and heavyweight artifact trees before ignore rules take effect, which inflates runtime on real repositories and produces misleading ETA feedback because skipped files still count toward totals. The same runtime area also references project-bundle Jinja2 templates that are missing from the packaged module artifact, so installed workflows can fail even when commands are present.
