refactor: improve type safety for fetch_instructions tool

- Export FetchInstructionsToolDirective type from tool-directives index
- Add FetchInstructionsToolDirective to main directives exports
- Update fetchInstructionsTool function to use specific type instead of generic ToolDirective
- Add proper type import in presentAssistantMessage for fetch_instructions handling

This improves type safety and makes the codebase more maintainable by using specific types instead of generic ones.
