# DEPLOY COMMIT: verifica alterações, documenta e faz push
#
# Fluxo:
#   1. Verifica se há alterações no repositório
#   2. Lê as notas do admin/DEV-NOTES.md
#   3. Monta mensagem de commit descritiva
#   4. Faz commit e push automático
#
# Uso:
#   admin/deploy.command              commit + push interativo
#   AUTO=1 admin/deploy.command       commit + push automático
#   DRY=1  admin/deploy.command       mostra plano sem executar
