Add JSON minification handling in worker

Add isJson helper and handle .json files specially: attempt to minify by JSON.parse+JSON.stringify and write result; on parse error fall back to writing the original file and mark the result as failed. Update result flags to reflect whether the file was minified, skipped, failed, or failed-skip so callers can distinguish outcomes. This ensures JSON assets are compacted and errors are handled gracefully.
