Migrate dynamic toolset to modelcontextprotocol/go-sdk

[Copilot]

Migrates the dynamic toolset (enable_toolset, list_available_toolsets, get_toolset_tools) from mark3labs/mcp-go to modelcontextprotocol/go-sdk. Part of #1428.

Changes

Schema Migration

• Converted DSL-based tool definitions to jsonschema.Schema structures
• Changed ToolsetEnum() from returning mcp.PropertyOption to []any for enum values

Handler Updates

• Return type: (tool, handler server.ToolHandlerFunc) → (mcp.Tool, mcp.ToolHandlerFor[map[string]any, any])
• Handler signature: func(ctx, request) (*mcp.CallToolResult, error) → func(ctx, *request, args map[string]any) (*mcp.CallToolResult, any, error)
• Parameter extraction now uses RequiredParam[T](args, key) instead of RequiredParam[T](request, key)

Tool Registration

Fixed EnableToolset to call RegisterFunc(s) on each ServerTool instead of non-existent s.AddTools():

// Old approach
s.AddTools(toolset.GetActiveTools()...)

// New approach  
for _, serverTool := range toolset.GetActiveTools() {
    serverTool.RegisterFunc(s)
}

Testing

• Added dynamic_tools_test.go with comprehensive test coverage
• Generated toolsnaps for schema validation
• Removed //go:build ignore tag - tools now included in build

Pull Request Overview

This PR migrates the dynamic toolset functionality (enable_toolset, list_available_toolsets, get_toolset_tools) from the mark3labs/mcp-go SDK to the modelcontextprotocol/go-sdk. The migration includes schema conversion from DSL to JSON Schema, handler signature updates, and fixing tool registration logic.

Key changes:

• Schema definitions converted from DSL-based mcp.NewTool() calls to explicit jsonschema.Schema structures
• Handler signatures updated to use new SDK's ToolHandlerFor[map[string]any, any] pattern
• Tool registration fixed to use RegisterFunc() method instead of non-existent AddTools()
