 * Resolve the generic surface infrastructure config.

 * Reads top-level `surfaces` first, then the legacy `modules.surfaces` block,
 * so both spellings work while the migration lands. Built-in surface intents
 * are deliberately not read here; they belong to the UI profile.
 *
 * The resolved shape mirrors the public `SurfacesConfig`, with every member
 * present: the presets are merged objects rather than optional, and `resolver`
 * is a function or `null` once a non-function value has been rejected.
