[agent\_craft] Agent modifies a file but the context still holds the old version of the file

Implement an 'invalidate and reload' mechanism: whenever an agent writes to a file, mark the previous in-context version of that file as stale and force a re-read \(or apply the diff to the in-context representation\) before the next read from that file.

Journey Context:
If an agent reads a file, then edits it, the context window contains both the original read and the edit tool call. If the agent needs to read the file again, it might get confused by the stale original read in the context and try to make edits based on the old line numbers. The context management system must ensure that only the latest version of a file is considered canonical, either by dynamically applying diffs to the context or by explicitly invalidating old chunks.
