feat: update edition to 2024

[Berrysoft]

Closes #541

[Copilot]

Pull request overview

This PR updates the Rust edition from 2021 to 2024 across the workspace, implementing all necessary code changes to comply with the new edition's stricter safety requirements and modern language features.

Key Changes:

• Updated edition to 2024 in workspace Cargo.toml
• Wrapped all unsafe operations in explicit unsafe blocks as required by edition 2024
• Standardized safety documentation comments to use uppercase SAFETY:
• Adopted let-chain syntax (if let ... && let ...) replacing nested if-let patterns
• Added explicit capture syntax (+ use<T>) to impl trait return types
• Removed redundant ref mut patterns in match expressions
