## Bug Fixes
- Fixes `astro dev` incorrectly starting in background mode for Warp terminal users. Hybrid environments like Warp are no longer treated as AI agents for auto-background detection.
- Fixes `astro dev --background --host` not listing the network addresses. The background server start output and `astro dev status` now show every exposed network URL, matching the foreground dev server.
- Fixes responsive image CSS overriding user styles defined inside CSS `@layer` blocks. The generated image styles are now wrapped in `@layer astro.images`, ensuring they have lower cascade priority than user-defined layers.
- Fixes `astro dev --background` failing on Windows with "Failed to spawn background dev server process"
