test: import Result from typer.testing instead of click

[bvanelli]

Summary

tests/test_cli.py imported Result from click.testing purely as a return-type annotation for the local invoke() helper. The project never declared click as a direct dependency — it was only present transitively because typer (pulled in via the cli extra) used to depend on it. Recent typer releases dropped the click dependency, so fresh CI installs no longer get click, and the import fails at test collection time, breaking the pipeline.

Switching to from typer.testing import Result fixes this without adding a new dependency. typer.testing re-exposes Result across the entire typer>=0.12.0 range declared in pyproject.toml:

• typer 0.12.0 → click.testing.Result (when click was still a transitive dep)
• typer 0.26.x → typer._click.testing.Result (typer now vendors click internally)

Verified empirically in both environments.

Test plan

• CI pipeline (test.yaml) passes on this branch
• tests/test_cli.py imports resolve without click installed
