fix(agent-team-web): scope vitest to src/ so it skips the Playwright e2e specs

ci-web's `test` (vitest run) globbed e2e/dashboard.smoke.spec.ts, which imports
@playwright/test (the Playwright runner, not vitest) and fails to load — "1 test
file failed" while the 44 unit tests passed. Restrict vitest's include to
src/**; Playwright keeps its own testDir (./e2e).
