Replace the single monorepo CI job with a dynamic matrix: a discover job enumerates workspace packages, then one job per package builds it (with its workspace deps), lints and tests in parallel (fail-fast: false). Chromium is installed only for the browser-mode suites (primitives, editor). Adds a 'test' script to @robonen/docs so its suite runs under the per-package model (the root vitest projects list isn't used by CI anymore).
vue/primitives runs vitest in browser mode (instances: chromium), so 'pnpm test' launches Playwright Chromium — which the CI runner doesn't have, failing the run after all 3320 tests pass. Add 'playwright install --with-deps chromium' before the test step in both CI and publish workflows.
