docs(polecat): remove push instructions for local-only branches (gt-cqw0n)

Phase 3 of heresy correction: polecat branches stay local, Refinery
accesses them via shared .repo.git.

Changes:
- templates/polecat-CLAUDE.md: Remove push from completion checklist
- mol-polecat-work.formula.toml: Remove push step from cleanup-workspace
- polecat.md.tmpl: Update landing rule for local branches
- refinery.md.tmpl: Change origin/polecat to local branch references
