Struct FileWrite 

pub struct FileWrite { /* private fields */ }

Capability that writes file contents with backup-before-mutate.

Every write creates a timestamped backup via BackupManager, enabling rollback through the undo system. The backup is created before the mutation, so a failed write still leaves a recoverable state.
