Release v0.31.0

0.31.0

Released 2026-04-21

Changed

• Upgraded wasmtime to v44 -- adapted the incoming HTTP request handler to the
  new Service::handle API (no longer returns a Task); response body streaming
  now keeps run_concurrent alive until hyper finishes reading via a
  BodyDoneWrapper sentinel
• Restructured the outbound HTTP handler (HttpDefault) around wasmtime 44's
  WasiHttpHooks / WasiHttpCtx split. Outbound requests now reuse a shared
  reqwest::Client with connection pooling and a 10s connect timeout (configurable
  via HTTP_CONNECT_TIMEOUT_SECS) instead of building a new client per request.
  A one-off client is only built when a client certificate is required
• Removed HOST header deduplication in favour of letting reqwest set the
  header itself
