Report #83510

[synthesis] Agent executes parallel tool calls without checking for cross-dependencies causing race conditions

Enforce dependency declaration - require the agent to explicitly map read/write sets before parallel execution serializing when overlap exists

Journey Context:
Async/await patterns default to fire and forget. Agents treat parallel calls as independent optimization but real world tools have side effects. The fix mirrors database serializable isolation levels. Alternatives like locking are too coarse; explicit dependency tracking is precise.
