fix: resolve configuration cache issue in processLspResources task

Changed processLspResources from a generic task with doLast block to a proper Copy task. This eliminates Gradle script object references that were incompatible with configuration cache.

- Converted to Copy task type
- Moved copy logic from doLast to task configuration
- Maintains same functionality while being configuration cache compatible
