Method iterateNodesByKind

src/db/queries.ts:1056–1063

* Stream every node of a kind one at a time (lazy) instead of materializing * them all like getNodesByKind. For unbounded kinds (`function`, * `method`) on a symbol-dense project the full array is gigabytes; the * dynamic-edge synthesizers only scan-and-filter, so they iterate to ke

(kind: NodeKind)

   * memory O(1) in the node count rather than O(nodes) (#610).
