## @thymian/rules-rfc-9110
A rule set that enforces HTTP semantics defined in RFC 9110 (HTTP Semantics). Validates that API requests and responses conform to standards for methods, status codes, headers, content negotiation, and caching directives — the same rules work across `lint`, `test`, and `analyze`.
## Installation
```bash
npm install @thymian/rules-rfc-9110
