Pull request overview

This PR addresses issue #1917 by cleaning up Clippy lints related to format/string operations. The changes modernize string formatting to use Rust 2021+ inline format arguments and eliminate unnecessary format!() calls.

Changes:

• Removed useless_format, uninlined_format_args, and to_string_in_format_args from allowed Clippy lints in Cargo.toml
• Converted old-style format strings (format!("{}", var)) to inline format arguments (format!("{var}"))
• Replaced format!("literal") with .to_string() or String::new() for better performance and clarity
