"""Tests for installing a bundle from a local artifact/path (T045).

The resolution-level tests are pure; the end-to-end test installs the bundled
``agent-context`` extension fully offline from a built ``.zip`` artifact,
proving the real in-process primitive dispatch (T044) works without a network.
