fix(cli): avoid click<8.2 incompatibility in progressbar hidden kwarg

[Alberto-Codes]

Users with click < 8.2.0 get TypeError: progressbar() got an unexpected keyword argument 'hidden' when running any docvet command. typer.progressbar() accepts hidden in its own signature but passes it through to click.progressbar(), which only added hidden in click 8.2.0. Since docvet declares typer>=0.9 (allowing click>=8.0.0), environments can resolve to click 8.0.x/8.1.x where the kwarg doesn't exist.

• Add _maybe_progressbar context manager that shows a real progress bar when show=True and yields a plain iterator when show=False, avoiding the hidden kwarg entirely
• Replace all 5 typer.progressbar(..., hidden=not show_progress) calls in _runners.py with _maybe_progressbar
• Update tests to mock _maybe_progressbar instead of typer.progressbar, add direct unit tests for the helper

Test: uv run pytest tests/unit/test_cli_progress.py -v

Closes #404

Review Focus

The _maybe_progressbar helper — confirms it correctly delegates to typer.progressbar only when show=True and never passes hidden.

Pull request overview

Fixes a CLI runtime crash in environments using click<8.2 by avoiding the unsupported hidden kwarg path when constructing progress bars via Typer.

Changes:

• Introduces _maybe_progressbar context manager to either show a real progress bar (show=True) or yield a plain iterator (show=False).
• Replaces all runner usages of typer.progressbar(..., hidden=...) with _maybe_progressbar(..., show=...) to preserve compatibility.
• Updates and extends unit tests to mock _maybe_progressbar and to directly test the helper’s behavior.
