chore(deps): add typescript as devDependency

Add typescript to enable vitest type checking during test runs.
Previously vitest's typecheck feature would fail with 'spawn tsc ENOENT'
because typescript was not installed as a dependency.

- Add typescript ^5.8.3 to pnpm-workspace.yaml catalog
- Add typescript: catalog:dev to package.json devDependencies
