- Implemented Updated column in the plan list rich output by extending
lifecycle_list_plans() in src/cleveragents/cli/commands/plan.py.
The column is inserted after the existing Project column and before
Elapsed to maintain logical grouping.
- Added updated_str using plan.timestamps.updated_at.strftime('%Y-%m-%d %H:%M')
for a human-friendly timestamp in local time.
- Added three Behave scenarios in features/plan_cli_spec_alignment.feature
to assert presence of Name, Updated, and Invariants columns.
- Added 'When I run plan list with no filters' step definition.
- Added list_columns() function to robot/helper_plan_cli_spec.py verifying
all three columns with partial header checks due to terminal truncation.
- Added 'Plan List Rich Output Includes Required Columns' test case to
robot/plan_cli_spec.robot.
