test(04-01): RED — search workspace scaffold + normalizer vector suite (T1-T9)

- add the search/ npm workspace (root workspaces + search:test/search:typecheck delegates)
- zero-dependency runner/harness copied from the bot/test precedent
- 9 named normalizer laws: rule vectors, symmetry, whole-token-only,
  slash preservation, glued split, vowel-drop, idempotence, folding,
  table-is-data (>= 47 rows, one generic builder)

All 9 cases fail while src/normalize.ts is absent — the RED gate.
