• Epic: #32675 - Remove Repackaged Dependencies

Risk Level: High

• Breaking Changes: High (search is core functionality)
• Testing Required: Comprehensive search testing
• Dependencies: Affects all search and indexing operations

Start by reviewing epic #32675 and the project's Elasticsearch and Lucene dependency declarations, then trace the search and indexing test coverage. Replace the repackaged clients with standard Maven Central versions, verify cluster connectivity, indexing, queries, filters, and performance, and confirm all tests and documentation are updated.
