feat: Divi module catalog, attribute paths, short form and lit/divi-catalog

Adds per-path attribute kind (text/richtext/code/url/image/color/enum/
onoff/number/list/icon), derived from Divi's field component metadata
where an attribute path names one unambiguously (module.paths() itself
is unchanged; kinds() is a new, separate lookup exposed as path_kinds
on lit/divi-catalog's module detail). This is not in the task-4 brief;
it is added because 2b's sanitization routing (ruling R3) needs a
metadata-derived field kind per attribute path. Verified live against
the full 100-module catalog (564/4358 paths resolve a kind; the rest
default to "unknown" and fall back to 2b's key-name routing).
