feat: expand KNOWN_RUNTIMES allowlist in dependency checker

Add common non-package terms that appear in stack documentation:
- Languages: Swift, Kotlin, Elixir, PHP, .NET/C#
- Databases: DynamoDB, Cassandra, Neo4j, Supabase, Neon
- Cloud: Vercel, Netlify, Railway, AWS services (S3, EC2, Lambda)
- Protocols: REST, GraphQL, gRPC, WebSocket, OAuth, JWT
- CSS/Build: Tailwind, Bootstrap, Webpack, Vite, esbuild
- Infra: Git, GitHub, Nginx, Linux, WASM

Prevents false DEPENDENCY_MISSING warnings for these terms.

Fixes #2
