docs(ext-api): refresh @example blocks + deprecate notify (W17.C/D/E)

- W17.C: refresh 5 stale @example blocks (types.ts, lifecycle.ts, node.ts,
  imperatives.ts ×2) — replace deprecated `async setup()` with
  `setup() { onMounted(...) }`; remove A1-removed `node.getWidget` from
  defineNode + NodeHandle.on migration examples; align imperatives examples
  with W17.B notify-toast verdict.
- W17.D: author ~37 new @example blocks across 9 files for sparse exports
  surfaced by W17.A audit. Pure JSDoc — zero exported-type diff.
- W17.E: add @deprecated JSDoc to notify() + NotifyOptions per
  D-notify-toast-consolidation (W17.B verdict (a) soft-deprecate).

Pure JSDoc — no signature, type, or export changes.
Phase A surface remains FROZEN at ee0537fdb5 (foundation surface SHA
unchanged; only @example / @deprecated text differs).

See research/dashboard-snippet-audit-2026-05-21.md (W17.A) for full
per-edit rationale.
