Refactor action plan verification command to plan verification

- Updated all references from `/workflow:action-plan-verify` to `/workflow:plan-verify` across various documentation and command files.
- Introduced a new command file for `/workflow:plan-verify` that performs read-only verification analysis on planning artifacts.
- Adjusted command relationships and help documentation to reflect the new command structure.
- Ensured consistency in command usage throughout the workflow guide and getting started documentation.
