## Description

Implement the `Sequential` ujsx component function. Structural container that renders children in order with sequential edges between consecutive siblings.

## Acceptance Criteria

- [ ] `src/component/sequential.ts` exports `Sequential` component function
- [ ] `Sequential` produces `UElement` with `type: "sequential"`
- [ ] Props: optional `id: string`
- [ ] Valid children: Operation, Sequential, Parallel, Conditional, Map
- [ ] Single-child Sequential is valid but degenerate (produces no edges)
- [ ] Re-exported from `src/component/index.ts`
- [ ] Unit tests: correct UElement shape
