Function mergeBlueprints

mergeBlueprints<
    U extends IncomingEvent = IncomingEvent,
    V extends OutgoingResponse = OutgoingResponse,
>(
    ...blueprints: (Record<string, any> | StoneBlueprint<U, V>)[],
): StoneBlueprint<U, V>
Merges multiple blueprints into a single application blueprint.

This function takes any number of blueprint objects and merges them into one, with later blueprints overwriting properties of earlier ones in case of conflicts. Deep-merges via @stone-js/config's deepMerge: plain objects merge recursively, arrays concatenate, and special objects (Date, Map, Set, class instances) are preserved instead of being flattened. Writes are guarded against prototype pollution. A single, shared merge implementation across the framework.
Type Parameters
- U extends IncomingEvent = IncomingEvent
- V extends OutgoingResponse = OutgoingResponse
Parameters
- ...blueprints: (Record<string, any> | StoneBlueprint<U, V>)[]
  An array of blueprints to be merged.
Returns StoneBlueprint<U, V>
The merged application blueprint.
Throws
- If any of the provided blueprints are not valid objects.
Example
```
const mergedBlueprint = mergeBlueprints(blueprint1, blueprint2);
```
