feat: sistema de personalidades enriquecido + agente template

Fase 1: Sistema de personalidades enriquecido
- Ampliar PersonalityCfg con role, backstory, expertise, limitations
- Añadir CommunicationCfg (formality, humor, personality, response_style, quirks, catchphrases)
- Crear tipos puros en pkg/personality/traits.go
- Implementar BuildPersonalityPrompt() para generar bloque de system prompt
- Integrar personalidad en agents/runtime.go (FromConfig + concatenacion al system prompt)

Fase 2: Agente plantilla
- Añadir campo Template bool a AgentMeta
- Filtrar agentes template en launcher (skip si template: true)
- Crear agents/_template/ con config.yaml completo y documentado
- Incluir TODAS las secciones (skills, shared_knowledge, schedules, security)
- agent.go minimo + prompts/system.md plantilla
- Actualizar dev-scripts/agent/new-agent.sh para copiar desde _template/

Fase 3: Ejemplos de personalidades
- Crear agents/_template/PERSONALITIES.md con 4 perfiles:
  * DevOps pragmatico
  * Analista meticuloso
  * Asistente amigable
  * Guardian de seguridad
