Pull request overview

This PR implements a Rust-based logging backend for the mw_log system. The implementation provides a core logging facade (mw_log), a string-based logger subscriber (mw_log_subscriber), and updates to existing formatting infrastructure to support the new logging system.

Key changes:

• Introduction of mw_log library providing logging macros and core logging traits
• Addition of mw_log_subscriber with a string-based backend implementation
• Updated module visibility and dependencies across logging components
• Addition of example applications demonstrating both custom and built-in logger usage
