Pull Request Overview

This PR introduces functionality to strip JSR meta module graph data when copying from the global cache to the local cache. Key changes include:

• Adding a helper function (jsr_url) to generate a JSR registry URL for use in tests.
• Modifying constructors in both LocalHttpCache and LocalLspHttpCache to accept a jsr_registry_url parameter.
• Implementing URL transformation logic to remove moduleGraph* keys from JSON metadata.
