Tools: Introducing graphql-complexity-validation

✨ Features ## 📦 Installation ## 🧠 How it works ## 🧪 Example ## 🔗 Links GraphQL is powerful, but without limits, complex queries can easily overwhelm your server. That’s why I built graphql-complexity-validation: a lightweight, framework-agnostic GraphQL validation rule that limits query complexity using native GraphQL validation. Each field has a cost (default: 1). Nested fields accumulate cost recursively. If the total exceeds the configured maximum, validation fails. No directives. No schema traversal. No framework lock-in.
