- Rewrite CHANGELOG.md to cover platform v1.0.0 and auth fix,
with reporting module history preserved as subsection
- Replace stale DOCUMENTATION_SUMMARY.txt with current project
structure and key decisions
- Rewrite MIGRATION_GUIDE.md to document legacy tool consolidation
with complete file mappings for hm_qc and video_qc
- Add legacy context headers to module docs (legacy_README,
legacy_DEV_SETUP, legacy_CLAUDE) pointing to main README
