feat(mcp): add GitHub repo support and tools display in MCP cards

- Support installing MCP servers from GitHub repos by converting 'github:user/repo' to 'git+https://github.com/user/repo.git' to avoid SSH issues and improve npm compatibility
- Display available tools in MCPCard with badges, showing up to 6 tools and total count for better visibility of server capabilities
- Remove unused onViewDetails prop and make uninstall button full-width for improved UI consistency
