feat: lit/library-make-global – node to global module, all or nothing (E10)

- NewLibraryEntry: spec and creation of a new library entry, shared by
  lit/library-save and lit/library-make-global (NewDraft, P7, StoredNodeGuard)
- UsageMatcher::referencesAny() (ruling Q7): a global entry never names any
  entry in any spelling Divi renders (P23/P24 forms, Divi 4 shortcodes inside
  Divi 5 values, values casting to 0); used by library-save scope global and
  make-global
- make-global: entry created, node replaced by GlobalInstance::of, page through
  DiviWriter::commit; refused or rolled-back page deletes the entry, a partial
  page write keeps it (the page may show it); sources are pages and posts only
