collect_submodules only takes .py, so packaged builds had no builtin coworkers.
Caught by inspecting the DMG — dev installs read them from the source tree.
The venv moves to .venv at the repo root and aisuite now installs from the
git-pinned dependency instead of a .pth into a parent checkout (bootstrap +
PyInstaller pathex). Updater/notary env files keep their one-directory-above-
the-repo convention. Guard the empty updater-overlay array expansion — under
set -u on stock macOS bash 3.2 it aborted every keyless (fresh-clone) build.
Imported from andrewyng/aisuite@1b4bbf303e
(contents of its platform/ directory, hoisted to the repo root).
Development history prior to this commit lives in that repository.
