Modernize Go code with latest style conventions

Applied automated modernization using gopls modernize tool to update:
- Replace interface{} with any type alias (Go 1.18+)
- Update range loops to use idiomatic range syntax
- Replace fmt.Sprintf with fmt.Appendf where appropriate

These changes improve code readability and align with current Go best
practices.
