feat(types): semilla con fields para 11 tipos + CLI --test-types-yaml

- examples/types.yaml: principal_field + fields para Person, Email,
  Domain, Phone, Org, IBAN, Account, Document, Address, Url, Table.
  44 fields totales. Documentacion del formato en cabecera.
- project_manager.cpp: seed con fields para los tipos basicos (fallback
  cuando no se encuentra examples/types.yaml).
- main.cpp:
  - Log de carga incluye conteo de schemas y total de fields.
  - --test-types-yaml <path>: smoke test que carga, serializa a temp y
    recarga. Compara entidades/relaciones/fields field-a-field. Salida
    PASS/FAIL con exit code 0/1. Permite verificar round-trip sin
    framework de tests.

Verificado: examples/types.yaml round-trip estable (11 entities, 44
fields, 6 relations).
