Mechanical path swap: AIUI's composables now live at aiui/packages/app/...
in this repo (git subtree import, D-19), not at the old separate clone
/home/archipelago/Projects/AIUI. Drops the "separate development branch to
push" language accordingly. Verified every retargeted path exists on disk
before rewriting; task content and must_haves are otherwise unchanged.
