Below is a concise technical summary of the changes proposed in this PR:
Introduces a standardized error handling mechanism across the TypeScript SDK by implementing the GalileoAPIError class and centralizing error validation within the BaseClient. This refactoring removes redundant error handling from individual service clients and enhances the GalileoLogger's resilience by replacing error throws with console logging in streaming modes.

Topic	Details
Logger Resilience	Enhance the robustness of the GalileoLogger in streaming mode by replacing error throws with console.error or console.warn calls. This prevents process interruptions due to internal logging issues and ensures that logging operations gracefully handle unexpected states.

Service Client Simplification	Simplify service-level API clients by removing redundant try-catch blocks and specific API exception classes, such as ExperimentTagsAPIException. This change leverages the new centralized error handling in BaseClient, reducing boilerplate and improving code clarity in individual services.

Centralized Error Handling	Refactor the BaseClient to centralize all API error handling logic, including parsing streaming responses and generating GalileoAPIError instances. This involves removing old error parsing methods, renaming validateResponse to validateAxiosResponse, and introducing new private methods like validateError and generateApiError to streamline error processing.

Structured API Errors	Implement the GalileoAPIError class, GalileoAPIStandardErrorData interface, and isGalileoAPIStandardErrorData type guard to provide a structured and consistent way to represent API errors, aligning with a predefined error catalog.
