Initial commit: in-process object_info cache + refresh UI

ComfyUI-Tenaciousload speeds up ComfyUI page loads for large model/LoRA
collections by caching the slow /api/object_info response in memory and on
disk (survives restarts) and serving it gzipped in ~milliseconds, instead of
rebuilding it (and freezing the event loop) on every load.

Adds a "Refresh Models / LoRAs" menu button, a graph node, and a
POST /tenaciousload/refresh endpoint to rebuild the cache after adding or
removing models. No external dependencies; no nginx/docker required.
