Validate Workflow Graph

Checks a workflow's node graph against the version 1 graph schema and returns either the errors to fix or a pass with node and edge counts and any warnings. It checks node ids, node types, edges, connection points and cycles, and says whether the graph has a final result node, without which the engine will not run it.

When you point it at a flow saved in your workspace, it also checks that each file node names a file that exists in that flow's folder. File nodes that do not match are silently dropped when the workflow is pushed, and a flow left with none falls back to using every example piece, so this catches a mistake nothing else reports.

You can pass the graph directly or by its path. It runs no part of the graph. It currently runs inside Syvon.
