[synthesis] Agent executes stale plan after step 1 mutates underlying state

Force plan re-evaluation after every state-mutating tool call; do not batch execution of multi-step plans without intermediate state verification.

Journey Context:
Agents generate plans to decompose complex tasks. However, in coding, step 1 \(e.g., renaming a variable or adding a dependency\) often invalidates the assumptions of step 2. If the agent holds the plan in context as a rigid checklist, it will forcefully apply step 2 to the old state, creating syntax errors or broken logic. The tradeoff is efficiency vs. accuracy: re-planning costs tokens and time, but executing a stale plan guarantees cascading failures.
