Fix progress feature: send progress only when batch is complete, not incrementally
- Remove incremental progress sending logic to avoid 'blasting the client' - Send progress only when prompt processing is complete (100%) - Add comprehensive test case with long prompt and small batch size - Test shows clear progress from 2.3% to 99.9% with 45 progress responses - Verify progress disabled functionality works correctly - Fixes GitHub issue #14685
