Add cursor-rules-pack: production-tested TypeScript rules

[oliviacraft]

Cursor Rules Pack

Adds the cursor-rules-pack plugin — production-tested Cursor Rules for TypeScript projects.

What's included

3 rule files organized by scope:

• rules/core.mdc — applies to all TypeScript files: dependency discipline, error handling, comments policy, naming conventions, file size discipline
• rules/nextjs.mdc — Next.js App Router: server components first, state management hierarchy, parallel data fetching, loading/error states
• rules/database.mdc — backend patterns: database query safety (always use select), API route security checklist, webhook security (signature + idempotency), Prisma best practices

Why these rules

Each rule addresses a specific failure pattern observed in production:

• Dependency discipline → prevents bloated package.json with abandoned packages
• Error handling → eliminates silent failures that are impossible to debug
• Database query safety → prevents accidental exposure of password hashes and tokens
• Webhook security → fixes the Website design system extraction #1 webhook bug: processing without signature verification
