Mocked unit tests for regenerateTreeIds, TemplateModal.addTemplateComponents,
and buildNodeTree each let a real bug ship (DataCloneError on duplicate/paste,
dropped template children, no-op AI section-replace/insert) because their
fake @craftjs/core query/actions never exercised Craft's real node shape
(data.type as a live component reference) or real parseFreshNode validation.
Adds src/test-utils/editorHarness.tsx, which mounts a REAL <Editor>+<Frame>
(no vi.mock('@craftjs/core') anywhere) via react-dom/client + act, plus the
jsdom shims Craft/this component library actually needs (ResizeObserver,
matchMedia, and an HTMLElement.prototype.innerText polyfill -- jsdom has no
native innerText, which Heading/TextBlock rely on to paint their text).
Adds 3 integration suites under src/test-utils/integration/ driving the real
useNodeActions/useKeyboardShortcuts, TemplateModal's real tree-build pipeline,
and the real useApplyAiResponse hook against a live EditorStore, asserting on
both the real rendered DOM and query.serialize()/exportBodyHtml output.
Red-proofed the duplicate/paste suite: temporarily reverted
regenerateTreeIds to structuredClone(oldNode.data) and confirmed both tests
fail with the historical DataCloneError before restoring the fix.
