/**
 * Best-effort framework component detection — dev builds only.
 *
 * React attaches a fiber to every DOM node it renders (`__reactFiber$*`).
 * Walking the `.return` chain finds the enclosing component, and dev builds
 * ≤ React 18 carry `_debugSource` (file/line injected by the JSX dev
 * transform — removed in React 19, where only component names survive).
 * Vue 3 attaches `__vueParentComponent`; SFCs expose `__name`/`__file` in
 * dev. Everything here is opportunistic: production/minified builds yield {}.
