[synthesis] Agent overwrites file changes due to internal scratchpad desynchronization with actual filesystem state

Before any write/edit tool call, mandate a git status or ls -la / head command to re-sync the agent's context with the ground truth of the filesystem, discarding previous scratchpad assumptions about file contents.

Journey Context:
Agents maintain a mental model of the codebase in their context/scratchpad. When they perform destructive actions \(like rm or git checkout\), or when external changes occur, their mental model becomes stale. If they act on the stale model, they might recreate a deleted file with old content, wiping out intermediate progress. Forcing a ground-truth re-sync before writes prevents catastrophic overwrites. This emerges from the intersection of filesystem mutability and agent stateful memory architectures.
