      Initiates the migration process. This method orchestrates the entire migration workflow: 1. Checks if pom.xml exists in the project location 2. Creates a minimal pom.xml if none exists (for standalone file migration) 3. Reads the project's POM file (existing or newly created) 4. Prepares the project for migration by adding OpenRewrite configuration 5. Executes the OpenRewrite migration recipe 6. Reads the modified POM file again to preserve changes made by OpenRewrite 7. Cleans up temporary migration artifacts (removes temp pom if created, or cleans existing pom)
      Throws:
      IOException - If there is an error reading, writing, or creating files
      org.codehaus.plexus.util.xml.pull.XmlPullParserException - If there is an error parsing the POM XML
      org.apache.maven.shared.invoker.MavenInvocationException - If there is an error invoking Maven
