- Add list-mode to rollback_plan: when no checkpoint ID given, list
available checkpoints instead of aborting (fixes feature file scenario)
- Add CleverAgentsError import to rollback_plan function scope
- Rewrite plan_cli_rollback_steps.py with correct mocking pattern:
patch get_container, use plan_app with ["rollback", ...] args,
:S parse modifiers to avoid AmbiguousStep, proper exception hierarchy
- Rename 4 conflicting @then step patterns to be rollback-specific:
"the rollback output should be valid JSON/YAML",
"the plan rollback should succeed",
"no rollback confirmation prompt should be shown"
- Fix JSON/YAML assertion steps to check format_output envelope
structure (data is nested under "data" key in the envelope)
- Update plan_cli_rollback.feature to match renamed step patterns

Adds end-to-end testing support for the new plan rollback CLI feature:
- plan_cli_rollback.feature introduces BDD scenarios for plan rollback, covering both listing a plan's rollbacks and restoring from a specific checkpoint.
- plan_cli_rollback_steps.py provides step definitions necessary to execute the feature tests and validate CLI behavior.
- Tests validate two modes: list mode (agents plan rollback <plan-id>) and restore mode (agents plan rollback <plan-id> <checkpoint-id>), ensuring atomic rollback, proper error handling, and correct output formatting.
- These tests integrate with the CLI testing framework and Milestone v3.3.0, aligning with the CLI component's roadmap.
