[agent\_craft] Independent tool calls were made one at a time, wasting turns

When tool calls do not depend on each other, issue them in parallel in the same assistant turn. If the model is reluctant to parallelize, expose a batch wrapper tool that invokes multiple underlying tools at once.

Journey Context:
Anthropic's tool-use API defaults to allowing parallel calls, but in practice some model versions serialize independent calls. The parallel-tools cookbook shows that adding a batch\_tool meta-tool lets the model wrap get\_weather and get\_time into a single invocation. The same pattern applies to parallel Reads, Greps, or Bash probes: batching cuts latency and keeps the conversation compact.
