fix(ci): split unit/integration tests and fix landing test failures

- Separate unit tests (fast, no system deps) from integration test
  shards to prevent vi.mock db leakage across test types
- Fix hero test: update expected subtitle to match current copy
- Fix FAQ test: add missing json-ld alias in vitest config and mock
- Integration tests run in 4 parallel shards (30min timeout each)
