[synthesis] Agent confidently repeats wrong assumptions for multiple steps after a single misinterpreted tool output

Add a 'state assertion' step after every tool call, forcing the agent to explicitly state what it just learned and verify it against the raw tool output before proceeding.

Journey Context:
When an agent misreads a tool output \(e.g., assumes a file was created successfully because the CLI returned 0, but it actually returned a warning to stderr\), it builds subsequent logic on a false premise. Because LLMs are autoregressive, the false premise becomes part of the context, making it highly probable to generate actions consistent with the false premise. Simply asking 'did it work?' isn't enough; the agent must extract the exact state change and verify it. This mirrors the 'read back' protocol in distributed systems and prevents error cascades.
