Transform-data syntax validation
Transform-data steps now validate JavaScript/TypeScript syntax at save and dispatch time—catching typos and parse errors before sandbox execution.

Flow validation runs a lightweight syntax pass over transform-data scripts so broken edits fail fast in the validator and API tests, not only when a run reaches the sandbox.
The check targets real-world TS-in-JS patterns you actually author in steps, which cuts down on “green save, red runtime” surprises.
