PaddleAPITest

Generate, expand, split, and validate PaddleAPITest API configuration cases from Paddle/PaddleFleet API names or existing seed config files. Use for creating broad 4096, 1M, and 0size case sets; increasing sampled shapes and parameter combinations; modeling public APIs or paddle._C_ops._run_custom_op schemas; preserving linked Tensor constraints; adding edge or intentionally invalid stability probes; and producing per-API config files with manifests.
