feat(docs): stop hiding half the component API — typed emits, exposes, flow guide
The per-part regex only saw defineEmits<{ inline literal }>(), so a named
interface — how Flow, Popover, Dialog, Menu and Drawer all declare their
events — extracted as zero emits, and defineExpose was not extracted at
all: 36 components' template-ref surfaces were invisible. Consumers
rebuilt what existed (nodeDragStop from @nodes-change, a renderless
child to reach fitView).

- extractor: one type-checking project per components package with a
  virtual <file>.vue.ts mirror per SFC, so cross-file emits interfaces
  (extends included) and expose spreads resolve through the checker —
  ...api expands into the composable's full return with its JSDoc
- parts gain exposes; emits/exposes members carry their JSDoc text;
  update:* model emits get a stock description
- UI: Description column on emits, an Exposes (template ref) table; MCP
  get_doc renders the same
- FlowRoot: JSDoc on every emit and exposed member
- new primitives guide page: building flow graphs — sizing, custom
  nodes, .nodrag, click family, instance API, edge labels
