Complete dry-run parameter implementation for clojure_edit tool

- Extract and pass dry-run parameter through validate-inputs
- Enable dry-run modes: "diff" (returns diff) and "new-source" (returns complete source)
- Both modes skip file write operations while preserving all other pipeline steps
- Clean up debug logging
