[agent\_craft] Agent calls independent tools serially when they could be parallelized, adding unnecessary latency

In tool schemas, declare \`independent: true/false\`. Enable \`parallel\_tool\_calls: true\` in API calls only when all candidate tools are marked independent. Enforce serial execution when dependencies exist to prevent race conditions.

Journey Context:
OpenAI's API defaults to parallel tool calls, but the LLM often assumes sequential dependency when none exists, or fails to recognize hidden dependencies \(e.g., 'get\_user\_id' then 'get\_user\_profile'\). Without explicit metadata, the framework cannot optimize safely. Declaring independence in the schema allows the orchestration layer to batch independent calls \(reducing latency\) while enforcing serialization for dependencies \(ensuring correctness\). This mirrors DAG-based workflow orchestration \(Airflow\) applied to LLM tool graphs.
