Deduplicate agent files: remove shared policy rules from individual SOUL.md

Stripped rules that are already in POLICIES.md from all 28 SOUL.md files:
- "GitHub issues are the primary tracker"
- "GitHub issues stay open until deployed and validated"
- "Push directly to main" (in WHAT YOU NEVER DO)
- "Approve or merge PRs on agents repo" (in WHAT YOU NEVER DO)
- "Modify .github/workflows" (in WHAT YOU NEVER DO)

Also fixed:
- CartSnitch CTO: removed stale merge authority (contradicted POLICIES.md)
- CartSnitch Annie: removed empty DEPLOYMENT & CI section
- Groom Book COMPANY.md: updated roster with all 6 agents
- PRI COMPANY.md: removed Samuel, added VP Product, updated models/adapters
