"""E2E tests for all queue/task operation kinds and install_model endpoint.

Covers the task kinds NOT tested in test_e2e_endpoint.py:
    - update (single pack)
    - fix (single pack)
    - disable / enable cycle
    - install-model (via /v2/manager/queue/install_model)
    - update-all (via /v2/manager/queue/update_all)
    - update-comfyui (via /v2/manager/queue/update_comfyui)

Requires a pre-built E2E environment (from setup_e2e_env.py).
Set E2E_ROOT env var to point at it, or the tests will be skipped.
