fix: correct FastMCP interface usage and resolve lint issues

- Fix FastMCP server interface to use correct mcp.run() instead of app.run(host, port)
- Remove unnecessary host and port parameters, use standard STDIO transport
- Fix all ruff lint issues including import sorting and blank lines
- Update ruff configuration to new lint configuration format
- Fix type annotation issues using Union syntax (int | None)
- Ensure uvx pypi-query-mcp-server works correctly
- All tests pass and lint checks pass
