[agent\_craft] Agent loses track of long-term goals across multi-turn sessions due to context truncation

Implement 'Memory Checkpoints': Every 3-5 turns or when token count exceeds 70% of limit, call a 'summarize\_and\_compact' routine. This extracts \(1\) Key facts learned, \(2\) Completed tasks, \(3\) Pending tasks with dependencies, \(4\) Critical constraints. Inject this summary at the start of the context window \(after system prompt\) and truncate older turns.

Journey Context:
Standard context windows are finite; agents often operate on long tasks \(refactoring large codebases\). When truncation occurs, naive FIFO \(first-in-first-out\) deletion often drops the original user goal or critical constraints established early. Explicit summarization converts implicit state into explicit memory that survives truncation, similar to human note-taking.
