Function buildIMFEconomicContext

buildIMFEconomicContext(
    countryCode: string,
    countryName: string,
    seriesByKey: ReadonlyMap<IMFMacroIndicatorKey, IMFSeries>,
    vintage?: string,
): IMFEconomicContext
Build an IMFEconomicContext from an indexed series map.

Each entry in seriesByKey should be keyed by the IMFMacroIndicatorKey so the builder can look up the mapping and produce a stable display row. Rows with no observations are skipped silently. When ANY indicator carries a forecast, forecastHorizonYear is set to the maximum forecast year so the caller can render a dashed overlay region starting from that year.
Parameters
- countryCode: string
  EU member state ISO2 code or IMF aggregate code.
- countryName: string
  Country display name.
- seriesByKey: ReadonlyMap<IMFMacroIndicatorKey, IMFSeries>
  Map of IMFMacroIndicatorKey to series.
- Optionalvintage: string
  IMF data vintage label (e.g. WEO-April-2026).
Returns IMFEconomicContext
Populated IMFEconomicContext (may have an empty indicators array).
