feat: v2.0 — rewrite completo con Pydantic v2, httpx, tipos estrictos y emulador SAT

- Nuevos módulos: models, exceptions, config, transport, xml_builder, client
- Servicios reescritos bajo cfdiclient/services/ (thread-safe, sin templates XML)
- Nuevo: SolicitaDescargaFolio, CFDIClient.poll_until_ready(), descargar_todos()
- 9 vulnerabilidades de seguridad corregidas (XXE, XML injection, token logging, etc.)
- 258 tests con emulador SAT (MockSatTransport) y cobertura >90%
- CI/CD: ci.yml + publish.yml (OIDC PyPI), dependabot, pre-commit, Makefile
- Eliminado código v1.x: webservicerequest, utils, signer y todos los .xml templates
- Workflows duplicados consolidados (continuous_integration/deployment eliminados)
