where is the tool-result on OutputProcessor as a ChunkType in the processOutputStream?

  /**
   * Process streaming chunks to detect and handle system prompts
   */
  async processOutputStream(args: {
    part: ChunkType
    streamParts: ChunkType[]
    state: Record<string, any>
    abort: (reason?: string) => never
    tracingContext?: TracingContext
  }): Promise<ChunkType | null> {
    const { part, streamParts, abort, state } = args

    const typeCounts = streamParts.reduce((acc, p) => {
      acc[p.type] = (acc[p.type] || 0) + 1;
      return acc;
    }, {} as Record<string, number>);
    
    console.log('Type counts:', typeCounts);
    console.log('==================');
...

Type counts: {
  'tool-call-input-streaming-start': 1,
  'tool-call-delta': 1,
