refactor: move MobileAction to option package and update imports

- Move MobileAction struct from uixt package to uixt/option package
- Delete uixt/driver_action.go file as MobileAction is now in option package
- Update all import statements across the codebase to use option.MobileAction
- Update ActionTool interface to use option.MobileAction in ConvertActionToCallToolRequest method
- Maintain backward compatibility while improving package organization
- Clean up code structure by consolidating action-related types in option package

Files affected:
- server/uixt.go: Updated imports and type references
- step.go: Updated imports and ActionResult struct
- step_ui.go: Updated all MobileAction references to option.MobileAction
- uixt/mcp_server.go: Updated ActionTool interface and removed detailed comments
- uixt/mcp_server_test.go: Updated all test cases to use option.MobileAction
- uixt/mcp_tools_*.go: Updated ConvertActionToCallToolRequest method signatures
- uixt/option/action.go: Added MobileAction struct definition
- uixt/sdk.go: Updated ExecuteAction method signature

 // ActionTool interface defines the contract for MCP tools
-//
-// This interface standardizes how UI automation actions are exposed through MCP protocol.
-// Each tool implementation must provide:
-//
-// 1. Identity and Documentation:
-//   - Name(): Unique identifier for the action (e.g., ACTION_TapXY)
-//   - Description(): Human-readable description for AI models
-//
-// 2. MCP Integration:
-//   - Options(): Parameter definitions with validation rules
-//   - Implement(): Actual execution logic as MCP handler
-//
-// 3. Legacy Compatibility:
-//   - ConvertActionToCallToolRequest(): Converts old MobileAction format
-//
-// Implementation Pattern:
-//
-//	type ToolExample struct{}
-//
-//	func (t *ToolExample) Name() option.ActionName {
-//	    return option.ACTION_Example
-//	}
-//
-//	func (t *ToolExample) Description() string {
-//	    return "Performs example operation"
-//	}
-//
-//	func (t *ToolExample) Options() []mcp.ToolOption {
-//	    return []mcp.ToolOption{
-//	        mcp.WithString("param", mcp.Description("Parameter description")),

-//	        // 2. Parse parameters
-//	        // 3. Execute operation
-//	        // 4. Return result
-//	    }
-//	}
-//
-// Benefits of this architecture:
-//   - Complete decoupling between tools
-//   - Consistent parameter handling
-//   - Standardized error reporting
-//   - Easy testing and maintenance
-//   - Seamless MCP protocol integration

 // parseActionOptions converts MCP request arguments to ActionOptions struct
-//
-// This function provides unified parameter parsing for all MCP tools by:
-//
-// 1. Converting map[string]any arguments to JSON bytes
-// 2. Unmarshaling JSON into strongly-typed ActionOptions struct
-// 3. Providing automatic validation and type conversion
-//
-// The ActionOptions struct contains all possible parameters for UI operations:
-//   - Coordinates: X, Y, FromX, FromY, ToX, ToY
-//   - Text/Content: Text, Content, AppName, PackageName
-//   - Timing: Duration, PressDuration, Milliseconds
-//   - Behavior: AntiRisk, IgnoreNotFoundError, Regex
-//   - Indices: Index, MaxRetryTimes, TabIndex
-//   - Device: Platform, Serial, Button, Direction
-//   - Web: Selector, PhoneNumber, Captcha, Password
-//   - AI: Prompt
-//   - Collections: Texts, Params, Points
-//
-// Parameters:
-//   - arguments: Raw MCP request arguments as map[string]any
-//
-// Returns:
-//   - *option.ActionOptions: Parsed and validated options struct
-//   - error: Parsing or validation error
-//
-// Usage:
-//
-//	unifiedReq, err := parseActionOptions(request.Params.Arguments)
-//	if err != nil {
-//	    return nil, err
-//	}
-//	// Use unifiedReq.X, unifiedReq.Y, etc.
-//
-// Error Handling:
-//   - JSON marshal errors (invalid argument types)
-//   - JSON unmarshal errors (type conversion failures)
-//   - Missing required fields (handled by individual tools)
