feat: adiciona sistema de versionamento e releases automáticas

- Implementa versionamento semântico para imagens Docker
- Adiciona job de release automática no GitHub Actions
- Releases criadas apenas para tags na branch main
- Adiciona documentação de versionamento em docs/VERSIONAMENTO.md
- Suporte a tags semânticas (v0.1.0, v0.5.0, etc)
- Versionamento baseado em package.json e tags Git
