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 Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01At3V6SjwbMe6eMzVGW3Hs7
