Patch Changes

• #16224 5152bf8 Thanks @adrianhall! - Fix short-lived local sessions hanging instead of exiting after dispose()

  A Miniflare instance using shared local storage could keep the Node process alive after dispose() resolved, because a filesystem watcher on the dev registry directory was left running. A one-shot local command would do its work and print its result, then never exit — cf d1 migrations apply --local, for example, applied every migration successfully and still had to be killed. Disposal now releases the watcher reliably, so the process exits on its own.

• #16146 9f87de8 Thanks @armancharan! - Replay the request body when dispatchFetch() retries HTTP 421

  A known-length POST that receives 421 used to throw UND_ERR_REQ_CONTENT_LENGTH_MISMATCH. The retry aborted the connection before the response was finished, which dropped the body while keeping the original Content-Length. The abort from that retry is now ignored so the same bytes are sent again.

• #16221 9be5ec7 Thanks @jamesopstad! - Promote Miniflare v5 prereleases from alpha to beta.

  This aligns the Miniflare prereleases with cf and @cloudflare/vite-plugin.

• #16219 d232454 Thanks @petebacondarwin! - Honor X-Forwarded-Proto for incoming development requests behind TLS-terminating proxies

  Miniflare now uses the original client protocol when constructing URLs for network requests. This also prevents Wrangler from downgrading HTTPS URLs in response headers such as Location and WWW-Authenticate when a tunnel forwards requests over HTTP. Explicit programmatic request URLs and configured upstream origins remain authoritative.
