Function resolveModelConfig

resolveModelConfig(
modelPath: string,
fallback?: ModelConfig,
): Promise<{ config: ModelConfig; descriptor: ModelDescriptor | null }>
Resolve the ModelConfig from a model-descriptor.json file co-located with the ONNX model, falling back to a canonical default if no descriptor is found.

This is the single entry-point called by TimesFMModel.fromPretrained. It ensures the descriptor is the single source of truth for all architecture constants — no more hardcoded TIMESFM_25_CONFIG in business logic.
Parameters
- modelPath: string
  Path to an ONNX model file.
- fallback: ModelConfig = TIMESFM_25_CONFIG
  Config to use when no descriptor is found (default: TIMESFM_25_CONFIG).
Returns Promise<{ config: ModelConfig; descriptor: ModelDescriptor | null }>
The resolved ModelConfig and the parsed descriptor (if any).
