+ * Bridges a DOM element's `.value` property to a Vue reactive ref.
+ *
+ * This composable provides a clean, public API for extension authors to
+ * synchronize DOM widget values with Vue reactivity (and by extension, the
+ * `widgetValueStore`). It works by:
+ *
+ * 1. Intercepting programmatic `.value` writes via `Object.defineProperty`
+ * 2. Listening for user-driven `input` events on the element
+ * 3. Exposing a reactive `Ref<string>` that stays in sync with the DOM
+ *
+ * When the returned ref is written to, the DOM element's value is updated.
+ * When the DOM element's value changes (programmatically or via user input),
+ * the ref is updated.
+ *
+ * @param element - The DOM element to bridge (input, textarea, or select)
+ * @returns A reactive ref that stays in sync with the element's value
+ *
+ * @example
+ * ```ts
+ * // In a custom widget's getValue/setValue:
+ * const bridgedValue = useDomValueBridge(inputEl)
+ * const widget = node.addDOMWidget(name, type, inputEl, {
+ *   getValue: () => bridgedValue.value,
+ *   setValue: (v) => { bridgedValue.value = v }
+ * })
+ * ```
