fix(ci): 集成测试xdist限制为2个worker，防止DooD模式下OOM杀进程\n\n- 从 -n auto 改为 -n 2\n- DooD模式下nproc读到宿主机4核8线程=8worker\n- 每个worker有独立PG库+ffmpeg编码，内存开销大\n- 8worker直接触发OOM killer杀ffmpeg和worker进程\n- 2worker既能提速（~1.5x）又稳定

fix(ci): 集成测试并行模式下去掉coverage检查（xdist+cov不兼容）
fix: pytest-cov 6.x不支持--cov-omit参数，改用pyproject.toml配置
