Add prominent warnings about the mandatory gt done requirement:
- New 'THE IDLE POLECAT HERESY' section at top of both templates
- Emphasize that sitting idle after completing work is a critical failure
- Add MANDATORY labels to completion protocol sections
- Add final reminder section before metadata block
This addresses the bug where polecats complete work but don't run gt done,
sitting idle and wasting resources instead of properly shutting down.
