/**
 * Builds a native DeckGL tooltip for a COG (Cloud Optimized GeoTIFF) layer.
 *
 * Reads the raster pixel value for the active channel via {@link readCogPixelValues},
 * formats it according to `cogBitmapOptions.tooltipSettings`, and returns a
 * {@link NativeTooltipResult} object.
 *
 * Returns `null` when:
 * - `cogBitmapOptions` is absent or `disableTooltip` is `true`.
 * - No pixel values are available at the cursor position.
 *
 * @param params
 * @param params.info           - DeckGL picking info (typed loosely to access `info.bitmap`).
 * @param params.config         - Parsed datasource configuration for the layer.
 * @param params.verticalOffset - Fallback vertical offset (px) used when `tooltipSettings.offsetY`
 *                                is not set.
 * @returns DeckGL tooltip object or `null`.
