Pull request overview

This PR applies stricter Clippy linting rules across the entire codebase, making code more idiomatic and consistent with Rust best practices. The changes focus on improving code quality through automated linting suggestions.

Key Changes:

• Replaced lazy_static! with standard library LazyLock (Rust 1.80+)
• Changed function parameters from owned to borrowed types to avoid unnecessary clones
• Replaced expect() with unwrap() consistently (with added panic documentation)
• Added const qualifiers to functions that can be evaluated at compile time
• Used Self instead of explicit type names in implementations
• Simplified pattern matching and control flow
• Added panic documentation to functions using unwrap() or expect()
• Added workspace-level lints configuration to Cargo.toml files
