fix: address review feedback — observability, dedup, query-strip, catalog

Review items addressed:

1. Mirror video-failure warning in beginFrame path (was screenshot-only)
2. Fix resolveProjectRelativeSrc escape-fallback to use query-stripped
   cleanSrc instead of raw src for the normalize/strip arm
3. Export prepareFlattenedInnerRoot from @hyperframes/core/compiler and
   consume in the producer instead of duplicating the implementation
4. Use typed Window cast instead of (window as any) for __hfForceTimelineRebind
5. Regenerate docs/public/catalog-index.json with all 6 map blocks
6. Restore Maps nav group in docs.json (catalog generator had merged
   them into Data)
