fix(manifest): classify every Maven dependency scope as Maven does

 ### Fixed
 - Maven Socket facts honor artifact types that build extensions define, so they no longer list dependencies Maven doesn't resolve, or fetch files under the wrong extension.
+- Maven Socket facts no longer drop dependencies whose scope Maven 3 doesn't define, such as Maven 4's `compile-only` or `none`.
