Minor Changes

• #15567 a71237a Thanks @tpmmorris! - Add row-level email resend tools to the Local Explorer

  Routing captures can now be resent directly or loaded into the test email composer for editing. Routing rows expose and use a UUID-based capture ID for identity, detail lookup, and resend operations instead of relying on the email's Message-ID. Message-ID detail lookup remains available for compatibility, and resends preserve partial-capture warnings across replayed messages.

Patch Changes

• #15806 8fade73 Thanks @NuroDev! - Standardize Zod validation error output

  Format validation errors with Zod's built-in prettifyError() helper so Miniflare, Wrangler, the Vite plugin, and the Vitest plugin show consistent messages and property paths.
