🔧 Bug Fixes & Patches (6)

Prevents `App.match()` from throwing on request paths that contain an invalid percent-sequence.
Fixes an issue where editing a client-side component (e.g. with `client:idle`, `client:load`, etc.) caused an unnecessary full program reload of the backend during development.
Fixes a bug where static file endpoints using `getStaticPaths` with `.html` in dynamic param values (e.g. `{ path: 'file.html' }`) would fail with a `NoMatchingStaticPathFound` error during build. The `.html` suffix is no longer incorrectly stripped from endpoint route pathnames.
Fixes dynamic routes returning 500 "TypeError: Missing parameter" when using domain-based i18n routing in SSR.
Fixes `Astro.routePattern` to preserve original casing of dynamic parameter names from filenames. Previously, a file at `src/pages/blog/[postId].astro` would return `/blog/[postid]` for `Astro.routePattern` due to an internal `.toLowerCase()` call. It now correctly returns `/blog/[postId]`.
Fix an issue where dynamic routes would return the string `[object Object]` instead of the expected content, in certain runtimes.
