/**
 * adowire client — adowire:submit directive
 *
 * Uses event delegation on `document` to intercept submit events on forms
 * carrying a `adowire:submit` attribute. It:
 *   1. Calls `preventDefault()` to stop the native browser submission.
 *   2. Serialises form fields that have a `adowire:model` attribute into an
 *      `updates` object (keyed by the model path).
 *   3. Parses the `adowire:submit` attribute value for an optional method name
 *      (defaults to `"submit"` if the value is empty or boolean-like).
 *   4. Commits the action to the owning [adowire:id] component.
 *
 * Attribute value formats (same grammar as adowire:click):
 *   adowire:submit             → method: "submit", params: []
 *   adowire:submit="save"      → method: "save",   params: []
 *   adowire:submit="save(1)"   → method: "save",   params: [1]
