/**
 * A UUID that works everywhere praisonai-ts runs.
 *
 * `import { randomUUID } from 'crypto'` is a STATIC Node builtin import: in a
 * browser or webview the bundle dies at module load, before any code runs,
 * with no error boundary and a blank screen. That was issue #4437, and PR
 * #4438 fixed it for the two files on the Agent import graph -- leaving the
 * same import in 32 others, each of which re-breaks the moment anything
 * reachable from a webview touches it.
 *
 * `globalThis.crypto.randomUUID` is a straight substitution rather than a
 * polyfill: it exists in every supported webview and in Node >= 19. The
 * fallbacks below exist for older runtimes and are ordered by how much
 * entropy they can offer.
 *
 * The version and variant nibbles are set BY HAND in the fallback, which is
 * the part worth reading twice: getting the masks wrong yields a string that
 * looks like a UUID and is not one, and anything validating it rejects the id
 * far away from here.
