When the primary model supports vision natively (e.g., Claude Opus 4.5),
skip the image understanding call entirely. The image will be injected
directly into the model context instead, saving an API call and avoiding
redundant descriptions.

Move dynamic import of @mariozechner/pi-coding-agent into the try/catch so transient module resolution errors don't poison the model catalog cache with a rejected promise.
This previously caused Discord/Telegram handlers and heartbeat to fail until process restart if the import failed once.
