Create the document builder that parses providers.xml configuration files through org.apache.commons:commons-secure-xml. The secure factory enables FEATURE_SECURE_PROCESSING and installs a non-removable entity-resolver floor on every parser it produces: external DTD and entity lookups are resolved to empty content instead of being fetched, and internal entity expansion is bounded, regardless of the JAXP implementation on the classpath. Changes: - Add the commons-secure-xml dependency (1.0.0-SNAPSHOT until its first release) to commons-vfs2. - Route factory creation through SecureDocumentBuilderFactory in StandardFileSystemManager. Internal entities declared in a configuration file's own DTD subset still expand (setExpandEntityReferences stays on); only external content is affected. - Run the CI and CodeQL builds with -Puse-apache-snapshots (inherited from the org.apache:apache parent POM) so the commons-secure-xml SNAPSHOT resolves; CodeQL's autobuild receives the profile through MAVEN_ARGS.
