feat: WP-0004 T05 — SBOM ingested, workplan complete

Generated requirements.txt (23 entries) and ingested SBOM via
scripts/ingest_sbom.py --api-base http://127.0.0.1:18000.
Fixed repo local_path registration (worsch→tegwick) so consistency
check resolves correctly. All WP-0004 tasks done; workplan closed.
