[synthesis] Agent summarization of long context erases subtle error states, turning a failed multi-step process into a perceived success

Implement a scratchpad audit log that is exempt from summarization, explicitly tracking the boolean success/failure of every tool call and the exact error string, forcing the summarizer to include these immutable facts.

Journey Context:
When context windows fill up, agents compress history. LLM summarizers tend to optimize for narrative coherence. If an agent attempted to install a package, failed, but then found a workaround, the summarizer might condense this to 'Successfully installed package X.' This destroys the critical fact that the primary installation method failed, which might be the root cause of later runtime issues. Keeping an immutable, un-summarized structured log of tool outcomes prevents this historical revisionism.
