feat: añadir skills de Claude Code para create-agent y parallel-fix-issues

Dos skills declarativas para automatizar flujos complejos:

- create-agent: pipeline completo de scaffold + build + register + verify
  para nuevos agentes/robots Matrix, con templates para agent.go,
  config.yaml y system prompt.

- parallel-fix-issues: implementación concurrente de múltiples issues
  usando git worktrees y agentes paralelos, con análisis de dependencias,
  verificación por wave e integración ordenada a master.

Ambas skills incluyen templates y scripts auxiliares.
