# Automatic Version Bump Script
# ==============================================================================
# Bu script her build'de çalışır ve:
# 1. version.json'daki buildNumber'ı artırır
# 2. Backend ve Frontend'deki versiyon bilgilerini günceller
# 3. Değişiklikleri commit eder (opsiyonel)
#
# Kullanım:
#   ./bump-version.sh [--commit]
