Add MongoDB schema with Prisma 6.8.2 for tracking:
- ServerEvent: events per server (coffee chats, study groups, etc.)
- UserPairingHistory: user pairing records per server
- PairingRecord: individual pairing entries with event context
This enables smart grouping that avoids recent pairings per-event.
- Initialize pnpm project with TypeScript support
- Add standard ESLint and TypeScript configurations
- Create basic src/index.ts with sample export
- Set up GitHub Actions CI workflow
- Add prod.env with 1Password references
- Configure .gitignore for Node.js projects
