"""Step definitions for plan_cli_commands_r2.feature.

Targets remaining partial branches in
``cleveragents.cli.commands.plan`` (plan.py) - round 2, split 2 of 3.

Covers:
- ``use_action`` argument parsing: int/float/bool/string, missing '=',
  invalid automation profile, invalid actor overrides
- ``execute_plan`` auto-resolve: 0 plans / >1 plans / exactly 1
- ``apply_plan`` auto-resolve: same subcases
- ``list_plans``: invalid phase/state, empty result, project truncation
- ``revert_plan``: invalid to-phase, non-rich format
- ``plan_status``: no plans, non-rich list, non-rich single plan
- ``correct_decision``: invalid mode, empty guidance
- ``plan_diff``: correction flag

All step text uses the ``r2plan-`` prefix to avoid collisions.
