Rpa_Skills/tests/evals/run_eval.py

"""Seam 2 skill eval: run the skills on a fixture project with `claude -p`, then grade.

Usage (from the repo root):
    uv run --with pytest --with playwright python tests/evals/run_eval.py a-empty

Copies tests/fixtures/<fixture> to a temp folder, installs every rpa-dashboard-*
skill there as a project skill, and runs `claude -p` with the user's answers in the
prompt (`-p` can't answer questions). It then grades the reply, runs the Seam 1 page
check on the page it built, and writes tests/evals/results/<fixture>.json.
Exit code 0 means every check passed.
