[synthesis] Agent drifts away from original error context by sequentially applying version-incompatible fixes found via web search

Before applying a fix from a web search, enforce a version-check step. If the fix fails, revert to the original error state and original error message before trying another solution.

Journey Context:
Agents use search to resolve errors. But search results are often version-specific. Applying a fix for v2 to a v3 codebase creates a new error. The agent then searches for this new error, which might be totally unrelated to the original problem. This creates a drift where the agent's context fills up with irrelevant errors and fixes, poisoning its understanding of the original task. The synthesis is that sequential error resolution without state reversion turns a single solvable problem into a cascading context poisoning attack.
