Phase C: Prune FrenoCorp to only owned code after ShieldAI/Scripter migration

Removed ShieldAI artifacts:
- apps/api/, apps/web/, apps/mobile/
- packages/ (all 8 shared packages)
- services/voiceprint-ml/
- server/alerts/, server/webrtc/
- examples/

Removed Scripter artifacts:
- marketing/
- tasks/

Updated root configs:
- Renamed package.json from shieldsai-monorepo to frenocorp
- Updated tsconfig.json to include agents/ instead of src/
- Updated vite.config.ts aliases to reference agents/, analysis/, plans/
