fix(ci): exclude integration tests from default test run

Integration tests create an OpenShellClient at file scope which
tries to load mTLS certs — fails in CI where no gateway exists.
Re-add exclude to vitest.config.ts and use a separate config
(vitest.integration.config.ts) for test:integration script.
