• #13932 ebf4b24 Thanks @zebp! - Fix local Workflow startup when compatibility flags include experimental

  Miniflare now deduplicates compatibility flags for the internal Workflow engine service. This prevents wrangler dev from failing with Compatibility flag specified multiple times: experimental when the user's Worker already enables that flag.
