feat(core): consider choices and undefindable.

[samchon]

This pull request introduces several updates to improve the handling of potentially undefined or missing choices arrays in the core orchestration and utility modules. The changes enhance robustness by ensuring that code does not fail when choices is undefined, and also add a new test for validation error stringification.

Robustness improvements for handling choices:

• Updated all loops and array operations in call.ts, cancel.ts, and select.ts to use (completion.choices ?? []), preventing errors when choices is undefined. [1] [2] [3] [4] [5]
• Changed checks and assignments to use optional chaining and default values for choices, ensuring safe access and correct behavior when choices may be absent. [1] [2] [3] [4] [5] [6] [7]

Utility function enhancements:

• Modified ChatGptCompletionMessageUtil.ts and ChatGptCompletionStreamingUtil.ts to use choices ?? [] and optional chaining in array operations, improving error handling and consistency. [1] [2] [3]

Testing improvements:

• Added a new test file test_validation_error_stringify.ts to verify the stringification of validation errors using JsonUtil.stringifyValidateFailure.
