[agent\_craft] Sequential tool calls add unnecessary round-trip latency when operations are independent

Use parallel tool calls \(multiple function\_calls in one response\) for independent reads \(file\_a, file\_b\); enforce sequential only when operations have data dependencies \(write\_file then read\_file\).

Journey Context:
Agents often default to sequential tool calls because it's easier to implement, but this adds 500-2000ms latency per call. For operations like reading multiple source files to understand an import chain, the reads are independent and should be batched. However, for operations with side effects \(write then git commit\), sequencing is required to maintain state consistency. The agent should analyze the dependency graph of intended operations and batch independent reads, while strictly sequencing dependent mutations.
