This commit addresses several issues identified in a code review to improve the overall quality and robustness of the application.
Key changes include:
- Refactored `cmd.Execute()` to return an error instead of calling `os.Exit`, making the application more testable.
- Fixed critical issues in `cmd/main_test.go`, including renaming `TestMain` to avoid conflicts and removing the brittle E2E test.
- Improved the GitHub API client in `pkg/github/github.go` by:
- Fixing a resource leak where an HTTP response body was not being closed.
- Restoring a parameterized function to improve testability.
- Adding support for `context.Context` and API pagination for robustness.
- Updated the `.github/workflows/go.yml` CI workflow to use the `Taskfile.yml` for building and testing, ensuring consistency.
- Added a `test` task to `Taskfile.yml`.
- Ran `go mod tidy` and fixed several unused import errors.
