Splash rollup catches up with the family — 7 children, 20 sources
The ai-labs splash was rolling up 4 children while the tree had grown to 7 — corpora-builder, id-didi-sh, and the whole studies shelf were invisible. The sync script now understands three container shapes (apps/, client-sites/, and studies' direct children), and the rollup carries 525 context-v files from 20 sources.
