## Bug Fixes
- Fixes a bug where remote image dimensions were not validated during static builds on Netlify.
- Fixes `--port` flag being ignored after a Vite-triggered server restart (e.g. when a `.env` file changes)
- Fixes the `/_image` endpoint accepting an arbitrary `f=svg` query parameter and serving non-SVG content as `image/svg+xml`. The endpoint now validates that the source is actually SVG before honoring `f=svg`, matching the same guard already enforced on the `<Image>` component path.

```bash
npm install --save-exact astro@6.1.7
