Verify the IMAGES binding on a live Cloudflare deploy (Astro) #273

#270 adds the images binding (#222). Its tests cover the generated wrangler and Alchemy output, and /_image was checked on a desktop dev build. Nobody has deployed it to the edge yet.

Check

1. Make a fresh Astro 7 + @astrojs/cloudflare 14 app with an <Image> on a server-rendered page. Run rustybuns init and confirm IMAGES is in rustybuns.config.ts.
2. Run rustybuns plan, then deploy.
3. Request the page's /_image?href=…&w=32&f=webp URL. It should return a resized WebP (Cloudflare Images really transforms it), not the original PNG.
4. Destroy the stack afterwards.

Cost

The Worker is on the free plan. Images transformations: 5,000 unique a month are free, so a few requests cost nothing.

Done when step 3 returns a transformed image and the result is noted in FRAMEWORKS.md.
