Contributions summary:Jerry primarily worked on improving the security and stability of the `chip-tool` by fixing thread races and addressing various issues. They refactored and restructured code to prevent thread-related issues by implementing thread locking, removing usleep and global instance hacks and re-structuring the command execution flow. They also added PID to the log lines on Darwin & Linux platforms. Additionally, the user also contributed towards the cluster object support by introducing the concept of a `DecodableType` for cluster objects that provides object representations of various cluster elements.
