feat: add runtime configuration for Kefu Chat SDK

- Introduced `readKefuChatRuntimeConfig` and `setKefuChatRuntimeConfig` functions to manage runtime configuration for the Kefu Chat SDK.
- Updated `useKefuChatStore` to utilize the new runtime configuration functions instead of the previous widget config methods.
- Modified the SDK build process to compile TypeScript instead of JavaScript, enhancing type safety and maintainability.
- Updated the minified SDK file to reflect the changes in configuration handling and TypeScript compilation.
