Report #87808

[synthesis] Agent fixes downstream type errors locally instead of tracing back to modified upstream interfaces

Run a static type checker immediately after modifying any interface or exported function, and feed the global errors back before proceeding to the next task.

Journey Context:
Agents work file-by-file. If they change a function signature in utils.py, they might not realize main.py is broken until later. When the runtime error occurs in main.py, the agent attempts to fix it locally \(e.g., casting types\) rather than reverting the upstream change. Immediate global static analysis after interface changes prevents this cascade of partial fixes that obscure the true root cause.
