Overview

A tiny per-chat memory of which files an agent has read and at what last-modified time, so Tools::WriteFile can refuse to overwrite a file the model never read — or one that changed underneath it — within a session.

Built once per chat in Agent#chat and threaded into both Tools::ReadFile (which records) and Tools::WriteFile (which enforces). Scope is clobber safety within a session only: no versioning, no locking, no VCS semantics.
