improve tool registry

[Copilot]

Pull request overview

This PR refactors the tool registry and discovery system, replacing the old adapter-based architecture with a simpler, more direct approach. The changes consolidate tool registration into a new humcp package with a decorator-based system that auto-discovers tools at startup.

Key Changes

• New architecture: Removed the adapter layer (FastMCPFastAPIAdapter, RouteGenerator) in favor of a direct decorator-based tool registry with unified route generation
• Simplified tool registration: Tools now use @tool() decorator from src.humcp.decorator with automatic name generation from category and function name
• Streamlined server creation: Consolidated server initialization into src.humcp.server.create_app() with automatic tool discovery and both REST and MCP endpoint registration
