 * Create a local section from a name, guard, and handler map.
 *
 * Encapsulates the cast from makeExo's opaque return type to Section.
 * Use this when constructing sections for a sheaf; do not use it for
 * the dispatch exo produced by sheafify itself.
 *
 * @param name - Exo tag name.
 * @param guard - Interface guard describing the section's methods.
 * @param handlers - Method handler map.
 * @returns A Section suitable for inclusion in a sheaf.
