Splash catches up: augment-it, a Studies landing page, nested-pseudomonorepo rollup, and OpenPanel
ai-labs grew a fourth active child (augment-it) and three of memopop-ai's apps started shipping their own changelogs, but the splash didn't know it. This round teaches the rollup to recurse into pseudomonorepo children's `apps/*`, adds a dedicated `/studies/` landing page that reads each study's `.gitmodules` and README at build time, surfaces augment-it in every count and card on the homepage, and wires OpenPanel analytics the same way the other splash sites do it.
