DIALECT-02: Anchor a section, read it from .anchors

What it demonstrates

A standalone ^id under a heading binds at section level and surfaces via SectionView.anchors (not byAnchor).

Builds on: DIALECT-01: Anchor a block, resolve it with byAnchor

How it’s done

Commands, code, and output together; comments mark which is which.

## Overview
^v2-overview

Ships the parser rewrite.

// consume
doc.body.section("Overview").anchors;  // ["v2-overview"]
doc.byAnchor("v2-overview");            // undefined — section ids live on .anchors

Surfaces exercised

• SectionNode.anchors
• SectionView.anchors
• Doc.byAnchor (block-scoped)
