chore: migrar agentes a claude-code como provider primario

Cambia el provider primario de ambos agentes (assistant-bot y asistente-2)
de openai/gpt-4o a claude-code/sonnet.

Configuración aplicada:
- disable_tools: true — claude no ejecuta herramientas internas
- permission_mode: bypassPermissions — sin diálogos interactivos
- model: sonnet — modelo interno de claude -p
- fallback desactivado temporalmente para validar que claude-code funciona

El launcher ya ejecutó exitosamente con este config, confirmado en logs:
claude_code_response con content_len=279, cost_usd=0.023514.
