• #13613 2f3d7b9 Thanks @dario-piotrowicz! - Fix sourcemap warnings caused by references to files outside the package boundary

  miniflare's bundled sourcemap contained sources entries pointing into node_modules dependencies (zod, capnp-es, chokidar, etc.), which produced dozens of warnings in pnpm monorepos when tools like Vite or Vitest validated the sourcemaps at runtime. The build now inlines sourcesContent and patches any null entries left by upstream dependencies that don't publish their original source files
