[synthesis] Agent writes increasingly complex wrapper scripts to fix a broken generated file instead of rewriting the file

Inject a 'complexity budget' or 'iteration limit' per artifact, and explicitly prompt the agent to delete and rewrite files from scratch if patching fails more than twice.

Journey Context:
When an agent generates a large file and it fails, the file occupies a massive portion of the context window. Due to attention mechanisms, the model anchors on the existing text and attempts minimal deltas \(patches/wrappers\). These patches often compound the error. The tradeoff is context window economy \(patching is cheaper\) vs. correctness \(rewriting is better\). Forcing a delete breaks the attention anchor and resets the context weighting.
