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

What it demonstrates

A caret block-id (^id) terminating a block binds it for doc.byAnchor lookup.

Builds on: nothing — this is the first rung of Dialect: Anchors, Wikilinks, and Vault References.

How it’s done

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

db.md

## Decision
| Choice | Owner |
| ------ | ----- |
| SQLite | Sam   |
^db-choice

// consume
const doc = c.read(src, { path: "db.md" });
doc.byAnchor("db-choice")?.kind;   // "table"
