Safe upgrade#15711 b2bd27b Thanks @OliverSpeir! - Improves Astro core's dev environment handling for prerendered routes by ensuring route/CSS updates and prerender middleware behavior work correctly across both SSR and prerender environments.
This enables integrations that use Astro's prerender dev environment (such as Cloudflare with prerenderEnvironment: 'node') to get consistent route matching and HMR behavior during development.
#15852 1cdaf9f Thanks @ematipico! - Fixes a regression where the the routes emitted by the astro:build:done hook didn't have the distURL array correctly populated.
#15765 ca76ff1 Thanks @matthewp! - Hardens server island POST endpoint validation to use own-property checks for improved consistency
