- Create Roux.Parser with parseCookFile (splits paragraphs, treats
each as a plain-text step, no metadata parsing yet)
- Add emptyMetadata to Roux.Types for convenience
- Add test dependencies: hspec, tasty-golden, tasty-hspec
- Add ParserSpec with 4 tests covering single step, multiple steps,
empty input, and whitespace trimming
- Wire ParserSpec into test runner via tasty-hspec
