chore: sync company/ export snapshot with current configuration

- Update .paperclip.yaml: agents migrated to opencode_local adapter, cleaned up deprecated env var defaults
- Update agent AGENTS.md files: barcode-betty, checkout-charlie, deal-dottie, stockboy-steve (skills list removed from frontmatter per new export format)
- Add new memory files: barcode-betty/2026-04-10.md, savannah-savings/2026-04-07.md, savannah-savings/2026-04-08.md
- Update savannah-savings/memory/2026-04-06.md with latest content
