refactor: improve Asset Store compliance implementation with production-ready setup

- Remove automatic installation attempts on package import
- Always show setup wizard on package install/reinstall
- Integrate MCP client configuration as part of setup wizard process
- Ensure MCP client config window remains accessible via menu
- Remove testing components for production readiness
- Replace automatic installation with manual guidance only
- Add complete 4-step setup flow: Welcome → Dependencies → Installation Guide → Client Configuration → Complete
- Improve user experience with clear instructions and accessible client management
