Opus orchestrator for /ultra-skill-author-local. Sequential 5-phase pipeline:
validate source → concept-extractor → skill-drafter → ip-hygiene-checker
→ completion summary.
No retry logic, no parallelism, no automation (per brief Non-Goals). Each
phase consumes the previous phase's output. --quick mode skips IP-hygiene
with a BIG WARNING for testing the drafting pipeline in isolation.
