feat(polecat): Add bulk removal with --all and multi-polecat support (gt-hcc0)

- Add --all flag to remove all polecats from a rig: `gt polecat remove gastown --all`
- Support multiple rig/polecat args: `gt polecat remove gastown/A gastown/B`
- Report summary of removed polecats and any failures
- Validate that --all is not used with rig/polecat format
