[synthesis] Parallel tool call failures cause agent to conflate success and error states

Disable parallel tool calls for mutating or dependent operations, or enforce strict result-to-call mapping by forcing the agent to process each tool result sequentially in its reasoning step.

Journey Context:
Parallel tool calls save latency but destroy the agent's ability to track causality. If read\_file\(A\) and delete\_file\(B\) are called in parallel, and delete\_file fails, the agent might think A was deleted. The tradeoff is speed vs. causal clarity. For state-mutating actions, sequential execution is strictly required to maintain the agent's causal model of the environment.
