Struct GraphBuilder 

pub struct GraphBuilder { /* private fields */ }

Mutable scratch state for assembling a graph inside a GraphDsl closure.

Tracks registered stages, their ports, the edges wired between them, and any deferred wiring errors (raised by wire, which collects rather than short-circuits). finish consumes it into a validated GraphBlueprint.
