Reverts an earlier incorrect cleanup: click.option with
is_flag=False + flag_value="." is valid click syntax that
allows --cwd to work both with and without an argument:
--cwd → cwd="." (current directory)
--cwd /path → cwd="/path"
--cwd=. → cwd="."
--cwd --flag → cwd=".", flag=True (correctly parsed)
Without these parameters, --cwd requires a value and
--dangerously-skip-permissions would be misread as the cwd.
