+Reduce the installed bundle sizes of Wrangler and Miniflare
+
+Wrangler now resolves bundled workspace dependencies from source during monorepo builds so unused exports can be removed. Miniflare, its shared CLI and container dependencies now use granular `@cloudflare/workers-utils` entry points instead of loading the package barrel, reducing the raw Wrangler and Miniflare artifacts by 6.16 MiB (31.4%) and 1.06 MiB (22.9%) respectively without changing runtime behavior or installed dependencies.
