Report #102783

[synthesis] Agent keeps executing an obsolete plan after the environment has changed

Revalidate plan preconditions at each step, not just at start; if a precondition fails, halt and replan rather than patching the plan inline.

Journey Context:
Agents generate plans at the beginning and then execute with commitment bias. A file that existed when planning may be gone; an API that was reachable may now 503. The failure mode is not lack of planning but lack of re-planning triggers. Precondition checks are the re-planning trigger; without them, the agent treats every obstacle as a local exception.
