 ### Step 3: Implement Rollback Tracking (Crucial)

 To ensure the user can seamlessly use `b rb <name>`, all manual modifications must be tracked:
- When extracting binaries to `~/.local/bin/`, use `track_file "$HOME/.local/bin/binary"`.
+- When extracting binaries to `~/.local/bin/`, use `track_file "${BOOTSTRAP_BIN:-$HOME/.local/share/bootstrap/bin}/binary"`.
 - When creating directories like `~/.config/tool/`, use `track_dir "$HOME/.config/tool"`.
 - When running manual apt/dnf/npm commands, log their inverses: `add_rollback_cmd "sudo npm uninstall -g package"`.
 Note: `pkg_install`, `write_env_snippet`, and `write_alias_snippet` will automatically track themselves.
