v4.0.0

Breaking changes

New scoped assertion API

Every assertion is now result.<scope>.<predicate>() with .not for negation:

result.exitCode.toBe(0)
result.status.toBe(201)
result.stdout.toContain("Build completed")
result.stderr.not.toContain("error")
result.stderr.toContain("rule", { near: "file.ts" })  // proximity check
result.file("dist/index.js").toExist()
result.file("dist/index.cjs").not.toExist()
result.file("dist/index.js").toContain("Hello")
result.response.toMatchFile("expected.json")
await result.table("users").toMatch({ columns, rows })
