build,ci: consolidate output under build/ and switch CI to npm/oxlint/vitest

- Makefile: coverage -> build/coverage, integration sessions -> build/sessions,
  integration test binary -> build/smocker.test, clean removes build/ only, and
  the release tarball packages only `smocker` + `client` (not test/runtime output).
- Playwright output dir -> build/e2e (see playwright.config.ts).
- sonar coverage report path -> build/coverage/cover.out.
- CI: yarn -> npm (cache + `npm ci`), lint via `npm run lint` (oxlint), unit tests
  via `npm test` (vitest); ::set-output -> $GITHUB_OUTPUT.
- .gitignore: everything generated now lives under build/, so ignore just build/
  and node_modules/ (plus editor/OS files); drop the stale root-level entries.

The repository root now stays clean: builds, coverage, e2e reports and runtime
sessions all land under build/.
