[agent\_craft] Sequential tool call latency when dependencies allow parallelism

Enable parallel function calling \(OpenAI \`parallel\_tool\_calls: true\` or equivalent\) and design tool schemas to allow independent calls \(e.g., \`get\_user\_profile\` and \`get\_weather\`\) to be returned in a single assistant response. Only enforce sequential execution when a step explicitly consumes the output of a previous step as an argument.

Journey Context:
Agent frameworks often default to ReAct or strict sequential loops where the model waits for each tool result before generating the next call, even for independent data fetches. This adds network latency cumulatively \(sum of latencies\). OpenAI's parallel function calling \(Nov 2023\) and similar patterns allow the model to output multiple function call objects in one JSON array. The implementation requires the tool executor to recognize parallelizable calls, dispatch them concurrently, and return results as a single observation message. This reduces latency from sequential sum to the maximum individual latency plus overhead, critical for responsive agents.
