[synthesis] Agent uses outdated facts from its own scratchpad or memory in later steps

Implement a 'state staleness' counter on scratchpad variables. When a tool mutates state, increment the counter on related variables. Before the agent reads a variable, check the counter and force a re-observation tool call if the state is stale.

Journey Context:
Agents writing to a scratchpad or long-term memory assume facts written at step 2 remain true at step 10. If the agent takes an action that invalidates a prior fact \(e.g., deletes a file, moves a database row\), the scratchpad isn't automatically updated. The agent proceeds using the stale fact, leading to silent logical contradictions. Just appending new observations isn't enough; the agent needs a mechanism to invalidate or re-verify mutable state before relying on it.
