This pull request introduces support for valueFromParam in tool configurations, allowing parameters to derive their values from other parameters. This is a valuable feature for creating more flexible and dynamic tool definitions. The changes include robust validation logic to prevent self-referencing and missing parameter references, ensuring the integrity of tool configurations. Additionally, the integration of embedding models for semantic search capabilities, leveraging this new parameter referencing, is well-implemented and thoroughly tested. The updates to the CI configuration and integration tests demonstrate a comprehensive approach to adding this new functionality.

This PR introduces a new configuration field valueFromParam to the tool definitions. This feature allows a parameter to automatically inherit its value from another sibling parameter, mainly to streamline the configuration of vector insertion tools. Parameters utilizing valueFromParam are excluded from the Tool and MCP manifests. This means the LLM does not see these parameters and is not required to generate them. The value is resolved internally by the Toolbox during execution. 15101b1

This PR introduces a new configuration field valueFromParam to the tool definitions. This feature allows a parameter to automatically inherit its value from another sibling parameter, mainly to streamline the configuration of vector insertion tools.
Parameters utilizing valueFromParam are excluded from the Tool and MCP manifests. This means the LLM does not see these parameters and is not required to generate them. The value is resolved internally by the Toolbox during execution.
