Code Review

This pull request introduces a significant refactoring of the webOS platform layer, generalizing it for Linux and abstracting webOS-specific components. It also adds support for Matter 1.5 specifications, including new features like NFC commissioning and OTA updates. The changes improve the codebase by using more robust patterns, such as a managed GLib event loop instead of detached threads, better error handling, and a more modular design for BLE and mDNS services. My review focuses on ensuring the correctness and safety of the new and refactored logic. I've identified a few areas for improvement, including removing debug logs, adding a missing bounds check to prevent data loss, and correcting a risky integer comparison. Overall, this is a substantial and high-quality contribution.
