Buat fungsi categorizePipelineStep(step) yang menerima string nama step CI/CD dan mengembalikan kategorinya.

Rules:

• Mengandung "build", "compile", "install" → "build"
• Mengandung "lint", "format", "style" → "lint"
• Mengandung "test", "spec", "coverage" → "test"
• Mengandung "deploy", "release", "publish" → "deploy"
• Selain itu → "other"

Case-insensitive.

Hint

• Pipeline CI/CD punya tahapan: build, test, deploy.
• Kategorikan berdasarkan keyword: "compile" → build, "unit test" → test.
• Step yang mengandung "deploy", "release" → deploy stage.
