Module graph 

Phase 1: Directed graph construction from the .pedal netlist.

Builds a LayoutGraph where each component is a node and each net creates edges between the components it connects. Edge direction is inferred from component type and pin function (e.g., triode grid = input, plate = output).

Structs

LayoutEdge

A directed edge between two layout nodes.

LayoutGraph

Directed graph built from the .pedal netlist for layout purposes.

LayoutNode

A node in the layout graph (one per component + special anchor nodes).

NetGroup

A group of pins that are all connected (one electrical net).

Enums

PinDirection

Inferred direction for a component pin (used by layout).
