fix(repo): set proper turbo deps for test tasks

Root test scripts bypassed turbo entirely (vitest run), so workspace
packages were never built before their dependents' tests tried to import
from dist/. Additionally, examples/ used workspace:* deps but were not
in the pnpm workspace.

- Route root test scripts through turbo run test
- Change test.dependsOn from ^build to build so each package builds
  itself before running tests
- Add examples/* to pnpm-workspace.yaml
