Implement Undo Functionality

[BDVRTribe]

Summary

Develop the undo feature to reverse recent actions by reading from the event log. This feature will enhance error recovery and control over snippet/file changes.

Tasks

• Design logic to reverse actions based on log entry
• Add a parser to read the last log item
• Implement undo_last_action() function
• Add CLI command: --undo
• Ensure safety for destructive actions

Outcome

Undo capability is functional, robust, and well-logged. The CLI should allow one-step reversal of the most recent action.
