🤖 Augment PR Summary

Summary: This PR streamlines successful validate --verbose output.

• Removes the per-instance matches <schema> line after successful validations.
• Simplifies process_entry by dropping its now-unused schema display-path parameter.
• Eliminates the corresponding schema display-path calculation in validate.
• Applies the concise success format to both batched inputs and direct instance-file processing.
• Updates CLI integration-test expectations across files, directories, JSONL, YAML, stdin, and resolver scenarios.

Technical Notes: Failure reporting, JSON output, tracing, benchmarking, and validation summaries remain unchanged.
