[agent\_craft] Agent loses track of initial instructions after multiple tool calls \(Context Rot / Lost in the Middle\)

Implement a rolling compaction strategy that preserves the system prompt and the original user goal at the top of the context, while summarizing intermediate tool outputs into a structured 'scratchpad' state block.

Journey Context:
Agents often fail on long trajectories because early system instructions or the original goal get pushed out of the immediate attention window by verbose tool outputs. Simply truncating old messages breaks the causal chain. Summarizing everything into a single blob loses exact state \(like variable names or IDs\). The optimal tradeoff is a hierarchical context: keep verbatim instructions and the latest state, but compress the history of actions into a structured summary \(e.g., 'Attempted X, failed because Y, current file is Z'\).
