Add the missing --namespace/-n option to lifecycle_list_plans() in
plan.py, mirroring the existing implementation in list_actions() in
action.py. The service layer already supported namespace filtering;
only the CLI layer was missing the option.
Changes:
- Add namespace parameter to lifecycle_list_plans() with --namespace/-n
option flags and 'Filter plans by namespace' help text
- Pass namespace through to service.list_plans(namespace=namespace, ...)
- Update TUI Filters panel to display 'Namespace: <value>' when provided
- Add usage examples to command docstring
- Add 4 Behave unit test scenarios covering --namespace/-n option
- Add 2 Robot Framework integration tests verifying namespace filtering
ISSUES CLOSED: #2165
Renames `plan lifecycle-list` to `plan list` and `plan lifecycle-apply` to `plan apply` to align with the specification's canonical command names. Removes legacy V2 plan commands that occupied those names.
- Renamed CLI command registrations from lifecycle-list/lifecycle-apply to list/apply
- Removed legacy V2 apply and list commands (~200 lines)
- Updated apply shortcut in main.py to delegate to v3 lifecycle
- Added defensive null check for plan existence in apply command
- Updated 63+ test, doc, and benchmark files for consistency
Closes#881
