UOW-014: Create Integration Tests for End-to-End Workflows

[andhijeannot]

Overview

Phase: 5 - Testing
Priority: Medium
Estimated Effort: 8-10 hours

Problem Description

The codebase lacks end-to-end integration tests that validate complete workflows from template to generated project.

Acceptance Criteria

• End-to-end workflow tests from template input to project output
• CLI command integration testing
• Template registry integration scenarios
• Multi-platform testing scenarios
• Performance regression testing
• Error condition integration tests

Files to Modify

• test/integration/ (new directory)
• test/fixtures/ (new test templates)
• test/integration/workflows_test.go (new file)
• test/integration/cli_test.go (new file)

See roadmap/phase5-testing/UOW-014-integration-tests.md for detailed implementation plan.
