@copilot can you add a ci workflow

@copilot can you add a ci workflow

I've added a comprehensive CI workflow that runs on pull requests and pushes to main. The workflow includes:

• Testing with Go 1.23
• Code quality checks (go vet, go fmt, golangci-lint)
• Building the project
• Running tests with race detection and coverage reporting
• Dependency caching for faster builds
• Coverage report artifacts

I also fixed Go formatting issues in the test files. The CI workflow is now ready to ensure code quality and catch issues early. See commit 5811d44.

@copilot this project had a massive overhaul, can you rebase and re-implement based on the new project structure

I've successfully rebased onto the latest main branch (after the project overhaul) and re-implemented the mock tests based on the new project structure.

Changes Made:

• Rebased branch to commit f033780 (latest main with project overhaul)
• Added github.com/h2non/gock v1.2.0 for HTTP mocking
• Created comprehensive mock tests in internal/api/rest_client_test.go with 85.9% code coverage
• Tests cover all major RestClient methods: ListProjects, GetProject, GetProjectStatistics, GetGroupByPath, and helper methods
• Updated .github/workflows/build.yml to include test execution, code quality checks (go vet, gofmt), and coverage reporting

Test Results:

PASS
coverage: 85.9% of statements
ok      github.com/mona-actions/gh-gitlab-stats/internal/api    0.006s

All 11 test cases pass successfully. The implementation is complete in commit 37bd24b.

Note: There's a branch history conflict preventing automatic push due to the diverged commit history between the old PR (based on pre-overhaul code) and the new implementation (based on post-overhaul code). The PR may need to be recreated or the remote branch reset to accept these changes.
