Pull request overview

This PR updates the project's Rust toolchain from nightly to stable version 1.85 as the minimum supported Rust version (MSRV), and upgrades the msgpacker dependency from 0.4.3 to 0.4.8. The changes also include modernizing the code to use newer stable Rust features and cleaning up formatting configuration.

Changes:

• Updated Rust toolchain to stable and set MSRV to 1.85
• Upgraded msgpacker dependency from 0.4.3 to 0.4.8
• Replaced map_or with is_none_or and is_some_and methods (stable since Rust 1.82)
• Simplified lifetime parameters in trait implementations by removing redundant 'b lifetimes
• Added explicit type parameters to mem::transmute for improved clarity
