feat(websearch): enhance Gemini CLI integration, package manager detection, and WebSearch status

- Improve Gemini CLI integration in websearch hook: use gemini-2.5-flash & --yolo.
- Update `dev-install.sh` for better package manager (npm/bun) auto-detection.
- Introduce `displayWebSearchStatus` for improved user experience.
- Refactor `mcp-manager.ts` to track CCS-managed MCP servers.
