Implemented DocstringExampleValidator class in src/cleveragents/cli/docstring_validator.py that validates CLI command docstring examples to ensure positional arguments precede option flags and align with Typer signatures.
Added Behave feature file at features/cli_docstring_example_validation.feature containing scenarios for valid and invalid docstring examples and edge cases.
Added step definitions at features/steps/cli_docstring_example_validation_steps.py implementing Given/When/Then steps to drive validation and report mismatches.
Fixed the problematic docstring in src/cleveragents/cli/commands/plan.py (rollback_plan function) to reflect correct positional argument order and clearer usage.
The validator ensures that docstring examples have positional arguments before option flags, matching the actual Typer command signature.
