chore: uniform dependencies across workspace

[premsgr]

Summary

This change aligns dependency versions and build metadata across the monorepo so packages and the demo app resolve the same toolchain, and refreshes pnpm-lock.yaml accordingly.

Dependency alignment

• Vite stack: vite 7.3.1, @vitejs/plugin-react 5.1.4 across library packages, config, and demo.
• Node types: @types/node 25.3.1 everywhere it is used.
• jsdom: 27.0.1 (replacing mixed 25.x / 26.x) for consistent Vitest/jsdom behavior.
• Zod: 3.24.2 in demo, form, and user packages.
• validator: 13.15.26 (form).
• Root devDependencies: @commitlint/cli and @commitlint/config-conventional 19.7.1, turbo 2.4.4 (aligned with the version exercised after install).

Package metadata and TypeScript

• exports: add explicit "types" entries pointing at ./dist/src/index.d.ts for config, form, i18n, layout, ui, and user so consumers resolve declarations consistently with ESM/CJS entries.
• tsconfig.json: set "moduleResolution": "bundler" in package tsconfigs that were updated (config, form, i18n, layout, ui, user) for consistent resolution with the Vite-based setup.

Demo app

• Move @prefabs.tech/tsconfig from dependencies to devDependencies (build-time only).

Scripts / CI ergonomics

• test:unit: append --passWithNoTests where unit suites may be empty (form, i18n, layout, user) so turbo run test does not fail on empty unit/ folders.

Verification

Pre-commit hooks ran lint, typecheck, and test successfully on this branch.
