Function reconcileForecast

reconcileForecast(
model: TimesFMModel,
params: HierarchicalForecastParams,
): Promise<HierarchicalForecastOutput>
Forecast every node independently with TimesFM, then reconcile the stacked base forecasts across the hierarchy.

Steps:
1. Validate the hierarchy structure.
2. Build the summing matrix S.
3. Call TimesFMModel.forecast once for all nodes (batched).
4. Reconcile via the chosen strategy (MinT by default).
5. Reconstruct per-node quantile forecasts from the reconciled point forecast (proportional adjustment from base quantiles).
Parameters
- model: TimesFMModel
  A compiled TimesFMModel instance.
- params: HierarchicalForecastParams
  Forecast parameters including hierarchy definition, per-node input series, and horizon.
Returns Promise<HierarchicalForecastOutput>
A HierarchicalForecastOutput with per-node reconciled forecasts and the top-level (unreconciled) raw model output for backward compatibility.

Throws
if the hierarchy is invalid or any node is missing from the inputs map.
