Add async callbacks and Kronos integration to API

Introduces async callback support for command execution in spawn methods, adds registration/unregistration for update and startup callbacks, and improves logging and signal handling. Adds a new Kronos module and main entry point for initializing and running the API with Kronos integration. Refactors example scripts and updates VSCode launch configurations for new entry points.
