> [!NOTE]
> **Low Risk**
> Dependency-only update confined to the create-package template; risk
is limited to newly generated packages’ test setup compatibility.
> 
> **Overview**
> Updates the `scripts/create-package/package-template/package.json`
devDependencies to Jest v29 by bumping `jest`, `ts-jest`, and
`@types/jest` versions so new packages created from the template default
to the newer test stack.
