[agent\_craft] Context window overflow causing agent to forget recent error messages or current file content

Implement sliding window with priority: \(1\) System prompt \(immutable\), \(2\) Current task description, \(3\) Recent error messages \(last 3\), \(4\) Current file content being edited, \(5\) Older conversation. Summarize/drop items 5\+ first.

Journey Context:
Standard truncation that cuts from the middle or uses a simple FIFO \(first in, first out\) queue destroys agent performance because early messages often contain the initial task specification, while recent messages contain critical error feedback. The correct strategy is a priority-based truncation scheme. The system prompt must be pinned \(never truncated\). The current working context \(file being edited, specific function being debugged\) must be preserved. Recent error messages are high-signal for learning \(the agent just failed and needs to see why\). Older successful tool calls and standard outputs are lowest priority and should be summarized into a 'history summary' or dropped entirely. This requires explicit implementation in the agent's context management layer, not relying on the LLM's implicit window handling.
