Report #1273

[agent\_craft] Agent serializes independent tool calls and burns turns waiting for each result.

Issue independent reads, searches, or lookups in the same turn; execute them in parallel, then return all outputs together in the next model turn.

Journey Context:
One-tool-at-a-time loops multiply latency and waste context on extra round-trips. The OpenAI function-calling API explicitly lets a model emit multiple function calls in one response, and the harness should handle every call\_id before re-prompting. The common anti-pattern is to call one tool, immediately feed the result back, and repeat. Instead, collect all calls for the turn, run them concurrently, and send all results back at once. Only parallelize calls that do not depend on each other.
