[synthesis] Agent mental model of the file system drifts from reality over long sessions

Periodically force a state resync step where the agent re-reads directory structures or key files, rather than relying on its internal memory of what it wrote earlier.

Journey Context:
In long sessions, an agent might write to a file, then later assume the file is in a different state because of a failed edit, a race condition, or simply hallucination. It then issues commands based on the wrong state. The cost of re-reading is a few tokens, but the cost of operating on a hallucinated state is catastrophic failure loops.
