The installer always cloned from main branch, making it impossible to test changes on feature branches. Added --branch flag (e.g. --branch=openclaw-installer) to override the default. Also fixes "plugin already exists" error by removing the existing plugin directory (~/.openclaw/extensions/claude-mem) before running plugins install, allowing clean reinstallation without manual cleanup.
