Patch Changes

• #16403 5f82a56 Thanks @dependabot! - Update DEFAULT_COMPAT_DATE to 2026-10-22

• #16437 e651d7c Thanks @dependabot! - Update DEFAULT_COMPAT_DATE to 2026-10-23

  Use the bundled workerd release's compatibility date by default when scaffolding new projects or when no compatibility date is configured.

• #16476 8a30d8e Thanks @tannerlinsley! - Update Undici to 7.30.1 to prevent a malformed HTTP response from crashing development tools

  The updated shared dependency rejects excessive content encodings without leaving an unhandled stream error when the server closes the connection early. This fixes GHSA-xjj6-f33q-929c and keeps the matching Undici types on the same version.

• #16490 bcd618d Thanks @petebacondarwin! - Update Zod to 4.6.6 to address GHSA-mrhx-c7xc-m3w5

  The updated shared dependency fixes excessive memory consumption when validating oversized collections. This updates both the published Zod dependencies and the copies bundled into development tools and Workers.

• #16335 28cca4c Thanks @robingenz! - Fix Worker tests failing when CommonJS dependencies require packages with separate import and require entries on Vite 8. The fix needs Vite 8.2.1 or later; Vite 8.0.x, 8.1.x and 8.2.0 stay affected.
