/**
 * Roku SceneGraph XML extraction.
 *
 * SceneGraph components are XML files that declare:
 * - a component name + parent type  (`<component name="X" extends="Group">`)
 * - public fields/functions (`<interface> <field ... /> </interface>`)
 * - script includes             (`<script uri="pkg:/..." />`)
 * - nested child components     (`<children> <Label .../> </children>`)
 *
 * This file exposes two regex-based extractors — no XML parser dependency,
 * matching the style of every other extractor in src/ast/.
