feat: Automate AgentVibes installer invocation after BMAD install

Instead of showing manual installation instructions, the installer now:
- Prompts "Press Enter to start AgentVibes installer..."
- Automatically runs npx agentvibes@latest install
- Handles errors gracefully with fallback instructions

This provides a seamless installation flow matching the test script's
interactive approach.
