Patch Application Engine

This module implements the core orchestration logic for applying patches. The central class FtwPatch manages the transition from parsed diff data to actual filesystem modifications.

Core Functionality:

• Staging:

  Changes are first applied to temporary files to ensure atomicity.

• Backup Management:

  Handles mandatory file backups before any write operations occur

• Transaction Safety:

  Implements an ‘all-or-nothing’ commit strategy for multi-file patches.

Usage:

Initialize with an options object satisfying the ArgParsOptions protocol and call run().
