Is your feature request related to a problem? Please describe.
The current tools package lacks retrieval-augmented generation (RAG) tools, which could enhance KaibanJS’s capabilities in language model tasks.

Describe the solution you'd like
Integrate RAG tools within the kaibanjs/tools package to facilitate more advanced language generation functionalities.

Describe alternatives you've considered
Using external RAG libraries, but native integration would ensure better compatibility and ease of use within KaibanJS.

Additional context
Adding RAG tools will improve the framework's functionality and appeal for complex language generation workflows.
