Edit command in editor

[alvinunreal]

Before executing a command user is prompted for confirmation or edit.

When edit is selected, use Git like approach. Open the command in current user EDITOR instead of inline editor - which has bugs.

✅ Completed issue #76: Edit command in editor

Successfully implemented the feature to use the user's external editor (via $EDITOR) instead of the inline editor when editing commands.

Task List:

• Investigate current codebase and find command confirmation/editing logic
• Locate inline editor implementation (found in internal/confirm.go)
• Implement external editor functionality (Git-like approach)
• Add error handling for when EDITOR is not set
• Test and commit changes
• Create PR

Changes Made:

Modified internal/confirm.go:64-126 to replace the inline readline editor with external editor support:

• Uses external editor from environment: Checks $EDITOR and $VISUAL environment variables
• Smart fallback: Automatically finds common editors (vim, vi, nano, emacs) if env vars not set
• Git-like behavior: Creates a temporary file with the command pre-filled for editing
• Proper terminal handling: Connects stdin/stdout/stderr for full terminal editor support
• Error handling: Provides clear error messages when no editor is available

The implementation follows Git's approach for editing commit messages, making it familiar and reliable for users.
