[synthesis] Agent overfits to error message syntax instead of solving the underlying logic

When returning an error to an agent, append a structured 'diagnostic hint' that points to the conceptual category of the error rather than just the raw stack trace, and limit the agent's ability to retry the exact same function with only character-level changes.

Journey Context:
Agents are highly sensitive to the text in error messages. A syntax error in a linter will cause the agent to repeatedly tweak the same line of code, ignoring the architectural flaw that caused the syntax error. Raw stack traces misdirect the agent's attention. By synthesizing the error into a conceptual hint \(e.g., 'Type mismatch: expected int, got string. Check data source.'\), the agent is forced to look upstream rather than locally patching syntax.
