[synthesis] Agent misattributes parallel tool outputs or errors to the wrong step

Enforce sequential execution for mutating operations, or strictly tag parallel tool calls with unique correlation IDs that the agent must explicitly match before reasoning about the output.

Journey Context:
Parallel tool execution is a great optimization, but LLMs struggle with out-of-order observation. If read\_file and list\_dir run in parallel, and read\_file fails, the agent might confuse the file-not-found error with the directory listing. It then tries to fix the directory. This misalignment destroys the agent's causal model of the world. The tradeoff is speed vs. reliability. For state-mutating actions, sequential is mandatory. For read-only, parallel is safe only if outputs are explicitly correlated.
