[agent\_craft] Agent context rot from accumulated failed tool call traces

Implement a sliding window or summarization compaction that aggressively prunes failed/repeated tool outputs, replacing them with a single 'Attempted X, failed with Y' summary, while preserving the original task prompt verbatim.

Journey Context:
Agents often append every tool output to the context. If a tool fails repeatedly \(e.g., a syntax error in generated code\), the stack traces consume the context window, pushing out the original instructions. Naive truncation drops the system prompt. Summarizing failures preserves the signal \(what was tried and failed\) while freeing tokens for the actual task, preventing the agent from looping on the same error.
