simplify: integration test filtering

- docs-only: skip entire integration job (job-level if)
- browser-only: skip IPC tests, run other integration tests (tests/runtime)
- otherwise: run all integration tests (tests/ipc tests/runtime)

Backend filter uses tests/** with !tests/e2e/** exclusion,
so new test directories are automatically included.
