/**
 * Helpers for finding elements in the flat [depth-idx] ref tree produced by
 * SocialBrowser.snapshot(). Ported from social-bot's bot/browser.py regex
 * model, where elements are located by role + label rather than CSS/XPath.
 *
 * The mental model: snapshot() returns a string like
 *
 *   [0-0] main: Timeline
 *     [1-0] article: post by user
 *       [2-0] link: Mar 16
 *       [2-1] StaticText: hello world
 *     [1-1] button: Reply
 *     [1-2] textbox: Post text
 *
 * …and these helpers find the refs via regex on that string.
 */

 * Find all refs matching a role and a label pattern.
 *
 * @param tree    The snapshot output string
 * @param role    AX role, e.g. "button", "link", "textbox", "article"
 * @param label   Regex source for the label (default `.*` — any). Substring matches count.
 * @returns       Array of ref ids like ["0-0", "1-3"] in document order
