[SUB-TASK] Fix TestUtilities Module Dependencies

[DrunkOnJava]

Sub-task of #90: Testing Infrastructure

Problem

TestUtilities module fails to import in test files, blocking all test compilation.

Error Details

import TestUtilities // Error: No such module 'TestUtilities'

Investigation Results

• TestUtilities package exists at correct path
• Package.swift properly defines the module
• Tuist configuration may not link it correctly

Tasks

• Verify TestUtilities Package.swift configuration
• Update Tuist Project.swift to properly link TestUtilities
• Ensure test targets have correct dependencies
• Fix import statements in all test files
• Add TestUtilities to all module test dependencies

Files to Update

• Modules/TestUtilities/Package.swift
• Project.swift (Tuist configuration)
• All *Tests.swift files with TestUtilities imports

Verification Steps

1. Run tuist generate
2. Open Xcode and verify TestUtilities appears in test target dependencies
3. Compile a single test file to verify import works
4. Run full test suite compilation

Acceptance Criteria

• TestUtilities imports successfully in all test files
• No "No such module" errors
• Test helper methods accessible
• Module visible in Xcode project navigator

Estimated Effort: 1-2 days
