Syntax and options for `uip api-workflow validate`, which checks an API Workflow JSON file's structure before packaging or running it.

uip api-workflow validate checks an API Workflow JSON file's structure — task shapes, expressions, and metadata — against schema, without executing it. Use it as a fast pre-flight check before run or pack.

For File to Base64 and Base64 to File activities, validation also checks that the task's script calls $helpers.file.fileToBase64(...) or $helpers.file.base64ToFile(...) with that exact name. Any other spelling is reported as an error, because the run would fail with "is not a function".

When validation passes with warnings, Data adds a Warnings field summarizing the count and each warning's path and message. When validation fails (errors present), the command exits non-zero and reports a Failure result whose Instructions field lists every issue found, each tagged [error] or [warning] with its JSON path.
