Report #1535

[agent\_craft] Agent re-reads entire large files after every minor edit, wasting context window and tokens

Implement a diff-based context update. Instead of re-reading the whole file, apply the edit and return a confirmation \+ diff, or maintain an abstract syntax tree \(AST\) representation of the file in memory that gets patched.

Journey Context:
Many agents operate in a loop: read file, edit file, read file again to verify. For large files, this consumes massive context. If the agent knows the exact edit it made \(e.g., replace lines 10-15\), it doesn't need to re-read the whole 1000-line file to verify. It can just run a linter or test. If it needs state, maintaining a shadow AST or using diff-based state saves context space.
