This pull request introduces a new integration with Seltz AI, providing a powerful web search tool for large language models. This enhancement allows LLMs to access up-to-date web knowledge with source URLs, significantly improving their ability to answer questions and perform real-time reasoning.

• Configurable Search Parameters: The Seltz Search tool supports various configurable parameters such as 'Max Documents', 'Context', and 'Profile' to refine search queries and results.

Code Review

This pull request introduces a new Seltz Search tool integration, which is a valuable addition. The implementation is well-structured, including the credential definition, the tool node, comprehensive unit and integration tests, and clear documentation. The code quality is high. I have one suggestion to improve robustness by adding an explicit nullish check for the Seltz API key to provide a clearer error message to the user in case of misconfiguration.
