Report #11045

[agent\_craft] Agent loses track of multi-step plan when context window fills up and intermediate steps are summarized away

Externalize the execution plan and state machine to a local file \(e.g., plan.md or state.json\) and have the agent read/update it via tools at the start and end of every step.

Journey Context:
Complex refactoring requires a multi-step plan. If the plan exists only in the context window, summarization or context overflow will corrupt or erase it. By writing the plan to the filesystem, the agent achieves persistent state. The context window becomes a transient scratchpad, while the file system holds the ground truth of the plan. Tradeoff: adds file I/O overhead, but guarantees the agent can recover its train of thought even after a context reset.
