Enhance Documentation Using JSDoc/TsDoc Standards

[h0ngcha0]

The SDK codebase would benefit from consistent, high-quality documentation to improve maintainability, ease of use, and on-boarding for new developers. To achieve this, we propose adopting JSDoc and/or TSDoc standards throughout the project. This will provide a standardized way to document functions, classes, parameters, return types, and modules, making it easier to generate comprehensive, up-to-date documentation.
