Bump typescript to 5.8, @types/node to 22, add jest-util

Update typescript from 4.9.5 to 5.8.3 and @types/node from 20.10.4
to 22.x to resolve type compatibility with jest 30 and ts-jest 29.
Add jest-util as explicit devDependency since ts-jest requires it
as an optional peer dependency that npm does not auto-hoist.
