feat(legal-sources): add OSHA machinery safety standards + international norms mapping

OSHA 29 CFR 1910 Subpart O (1910.211-1910.219) — complete machine guarding requirements. US federal law, public domain. International norms mapping table: China GB/T, Korea KS, India BIS equivalents to ISO/EN standards. Unfortunately all countries protect ISO copyright even for identical national adoptions (IDT). Only OSHA provides truly free machinery safety content. EU Excel harmonised standards list included for reference. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
