Implement SEP-986: Tool Name Guidance

[felixweinberger]

This is a tracking issue for implementation of SEP-986.

Summary

This SEP establishes clear guidelines and format specifications for tool naming conventions within the MCP protocol. The TypeScript SDK needs to implement validation for tool name formats, provide clear error messages when tool names don't follow the specified patterns, and ensure consistency with the standardized naming conventions to improve cross-implementation compatibility and prevent naming conflicts.
