Image Remove Background

This removes image backgrounds and outputs transparent PNGs, useful for product shots, profile pictures, or anything you're compositing later. It wraps the agent-media CLI and supports three providers: a local Transformers.js option that runs on CPU without API keys, plus Fal and Replicate for cloud processing. The local provider is decent for quick jobs but you'll want Fal's birefnet model if you need high resolution output, since it supports custom resolution parameters. Returns a JSON response with the output path and file info. The mutex lock error on local runs is apparently harmless, which is the kind of quirk you just learn to ignore.
