[RFC-ADN-01] Normalizar nomenclatura de proyectos

- Directorios: PascalCase (p2601_dasuten → P2601_Dasuten)
- Planes: numeración pura (P2601_6.1.A → P2601.06.01)
- Sin caracteres especiales en nombres de archivo
- 07_proyectos.md: convención RFC-ADN-01 integrada, P2604/P2605 agregados
- evento:listar: nueva opción --detalle para descripciones completas
