[FEATURE] Undo Last Action

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

When working with Claude Code, sometimes a request results in unintended changes across multiple files.

Currently, the only way to revert is through manual git commands (git checkout, git stash, etc.), which can be error-prone and frustrating - especially when trying to undo changes from multiple requests or when the scope of what to revert is unclear.

Problem:
After a request makes unwanted changes, there's no simple way to undo
Manual git reverts require knowing exactly which files were modified
Multiple back-and-forth "undo" requests to Claude can cause confusion and further mistakes
Users may lose track of the original state they wanted to return to

Proposed Solution

Proposed Solution: Add an "Undo" button or /undo command that:

Reverts all file changes made by the last Claude action
Optionally, allows undoing multiple previous actions (undo stack)
Shows a preview of what will be reverted before confirming

Alternative Solutions

Additional Context:
Similar to how chat interfaces like ChatGPT have edit/regenerate, Claude Code could benefit from action-level undo
This would make iterative development safer and reduce anxiety about making experimental requests
