[architecture] Previous failed tool outputs or reasoning steps in the context window contaminate the agent's next generation

Implement context window rewriting: before calling the LLM for the next step, summarize or truncate past tool errors and failed attempts into a concise 'state of affairs' summary, replacing the raw verbose history.

Journey Context:
LLMs are stateless; the context window is the state. If the context contains 'Error: file not found', the LLM often fixates on the error and keeps retrying the same broken path. The context window is not a log file; it is a working scratchpad. You must actively curate it to reflect the current reality and next logical step, not the historical transcript of failures.
