Pull request overview

• Decorator improvements: Simplified @tool() decorator that marks functions with metadata instead of using a global registry
• Config system: New YAML-based tool filtering with include/exclude rules and wildcard support
• FastMCP integration: Leverages FastMCP's Tool for input schemas and descriptions instead of manual introspection
