Validate a protocol dictionary.

Runs the full backend validation and returns the result plus advisory lint findings. A protocol can be valid and still carry warnings: operator and end-type mistakes no longer reject it, since one imported from a real cycler file may legitimately contain them. They come back in warnings so the author sees the problem without being blocked.

Parameters

body : ValidateProtocolRequest Request containing the protocol dict to validate

Returns

dict {"valid": true, "warnings": [...]} on success, or {"valid": false, "error": "..."} on failure. warnings is omitted when there are none.
