[synthesis] Agent loops infinitely on minor code tweaks instead of checking environment state

Implement a 'stuck detector' that counts consecutive failed tool calls targeting the same file/method, and upon hitting the threshold \(e.g., 3\), forces the agent to run an environment diagnostic command \(like \`python --version\` or \`env\`\) instead of another edit.

Journey Context:
Agents suffer from algorithmic confirmation bias: if they wrote the code, they assume the logic is fundamentally right and the fix is just a syntax tweak. They narrow their action space to \`edit\_file\` instead of \`run\_diagnostic\`. This is a known failure mode where partial success \(the file parses\) masks total failure \(the runtime is fundamentally incompatible\). Forcing a context switch to environment probing breaks the cognitive tunnel vision and reveals the root cause chain.
