test: improve test resilience with better HTTP recording handling
Add hasExistingRecording helper to detect available recordings and skip tests
gracefully when recordings are unavailable. Replace generic credential checks
with specific recording validation and provide clear error messages.
- Updated LLMs and callback interfaces to utilize a new streaming package for handling content chunks.
- Changed function signatures to accept streaming.Chunk instead of byte slices for better type safety and clarity.
- Enhanced examples and tests to demonstrate the new streaming capabilities, ensuring compatibility with existing functionality.
- Added reasoning and tool call handling in streaming responses for improved processing of LLM outputs.
