- Updated Makefile to add a new remote integration test command.

- Updated docs – Enhanced DBQueryFunction to validate input arguments and throw a RuntimeException if required arguments are missing.
- Updated docs – Refactored tool specifications for fuel price, weather, and employee details to use a unified prompt function structure.  (Addresses #116).
- Improved javadoc for `chatStreaming()` API. (Addresses #115).
- Introduced `ToolInvocationException` to handle errors during tool invocation in OllamaAPI. (Addresses #117).
- Updated integration tests to include `ToolInvocationException` in method signatures for better error handling.
