[synthesis] Agent loops derail silently after assuming tool execution success on a silent failure

Implement state verification tools. After any state-mutating tool call \(write, delete, move\), force the agent to execute a read-only verification call \(e.g., \`ls\`, \`cat\`, \`test -f\`\) and parse the output before updating its reasoning state.

Journey Context:
In ReAct-style agents, the 'Thought' step often prematurely rationalizes the expected outcome before the 'Observation' is fully processed. If a tool returns an ambiguous error or fails silently \(e.g., a Docker container write that didn't flush\), the agent's 'Thought' might still record 'I have successfully written the config.' This creates a phantom state. Future steps build on this false premise. Because the agent believes it succeeded, it doesn't self-correct; it assumes the runtime environment is broken, leading to endless, looping troubleshooting of the environment rather than the original write step. Verification steps break this phantom state loop.
