go build ./...go test ./...The parser implements:
- Streaming data handling
- Buffer management with growth
- State tracking (initialized/done)
- HTTP/1.1 request line validation
- Method validation (uppercase letters only)
- HTTP response status code handling with defined constants (200, 400, 500)

$ curl http://localhost:42069/video -o video.mp4The server supports standard HTTP methods (GET, POST, etc.) with proper validation:
# GET request
$ curl http://localhost:42069/
# POST request
$ curl -X POST http://localhost:42069/
# Invalid method
$ curl -X INVALID http://localhost:42069/
HTTP/1.1 400 Bad RequestMIT
