# script/prepare-release: Prepare a new release by bumping version and creating tag
#
# This script:
# 1. Validates the version format (X.Y.Z)
# 2. Updates custom_components/tibber_prices/manifest.json
# 3. Commits the change with conventional commit format
# 4. Creates an annotated git tag
# 5. Shows you what will be pushed (you decide when to push)
#
# Usage:
#   ./scripts/prepare-release VERSION
#   ./scripts/prepare-release 0.3.0
#   ./scripts/prepare-release 1.0.0
