docs(plan): replace the too-slow regression gate in task 2 (#27)

test/test_cli.py drives full CLI analyses and exceeds ten minutes, which is

proves the same wiring in seconds.

+Do NOT run `test/test_cli.py` — it drives full CLI analyses and exceeds 10 minutes. Run a
+direct analysis over a small fixture instead:
+
+```bash
+uv run canpy -i test/fixtures/single_functionalities/decorators_and_hof -a 1 -o /tmp/t2check

+Expected: analysis completes; `entrypoint_report` is present with empty lists and no errors.
