Query functions now return plain data objects. Two renderers (render_human, render_json) handle output formatting. A single run_query dispatcher routes to the right data function by file type and query name, then main() calls the appropriate renderer based on --format. Eliminates duplicated *_json variants and the OUTPUT_FORMAT global. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
