Pull Request Overview

Adds support for a custom User-Agent header by centralizing HTTP requests and replacing direct URI.open calls.

• Introduce http_get wrapper that reads OPENFOODFACTS_USER_AGENT from the environment
• Replace all URI.open invocations with Openfoodfacts.http_get
• Bump Ruby version to 3.3.6 in .tool-versions

lib/openfoodfacts.rb:43

• The new http_get method is not covered by tests. Please add unit or integration tests to verify both successful responses and custom User-Agent behavior.

def http_get(url)

lib/openfoodfacts.rb:43

• [nitpick] Document the OPENFOODFACTS_USER_AGENT environment variable in the README or project docs so users know how to set a custom header.

def http_get(url)

lib/openfoodfacts.rb:44

• Missing require 'open-uri' in this file: without requiring open-uri, URI.parse(url).open will be undefined at runtime.

URI.parse(url).open("User-Agent" => ENV.fetch('OPENFOODFACTS_USER_AGENT', nil))
