Module node 

Uniform node contract, lifecycle, and step context.

Nodes are monomorphized by generics and const generics — there is no dynamic dispatch in the hot path. Port schemas and policies are type-encoded on each node.

Key types:

• Node — the core trait: step(StepContext) -> StepResult.
• StepContext — per-step runtime context (clock, telemetry, input/output edges, memory manager).
• StepResult — scheduling hint returned after each step.
• ProcessResult — result of processing a single message inside a node.
• NodeKind — categorical label (source, process, model, sink, …).
• NodeCapabilities — capability descriptor for device streams and degrade tiers.

Submodules:

• source — SourceNode trait for 0-input nodes.
• sink — SinkNode trait for 0-output nodes.
• model — InferenceModel adapter for inference nodes.
• link — NodeLink and NodeDescriptor wiring helpers.
• bench — test nodes (bench / test feature).
