Clean up FrenoCorp repo: move project code to correct repositories (FRE-4529)

- Removed literal $AGENT_HOME/ directory artifact
- Moved Lendair iOS code to ~/code/lendair/iOS/Lendair/
- Moved marketing/ to ~/code/scripter/
- Moved ShieldAI workflow doc to ~/code/ShieldAI/
- Moved CI/CD workflows and load-test scripts to ~/code/lendair/
- Moved web configs (vercel.json, .env.example, index.html) to ~/code/lendair/web/
- Removed root-level project configs (package.json, tsconfig.json, vite.config.ts, etc.)
- Removed shared/exports/ and scripts/
- Updated all 8 agent AGENTS.md files with Repository Rules section
- Clarified: FrenoCorp is for agent notes/memories/plans only, not project code
