# PedScribe release helper — one command to tag a new version.
#
# Usage:
#   scripts/release.sh 6.1.1                 # bump to 6.1.1
#   scripts/release.sh 6.1.1 --push          # also git push + tag push
#   scripts/release.sh 6.2.0 --push --gh     # also create GitHub release
#
# What it does:
#   1. Updates version in root package.json
#   2. Updates version in mobile/package.json
#   3. Updates versionName + bumps versionCode in Android build.gradle
#   4. Commits the version bump
#   5. (optional) git push + push the new tag
#   6. (optional) create a GitHub release via gh CLI
#
# It does NOT:
#   - Build the Docker image (run `docker compose build`/`up -d` yourself
#     or wire it to a deploy script / CI hook)
#   - Build the Android APK (run `cd mobile/android && ./gradlew ...`
#     yourself). This script just marks the version so the build tags
#     correctly.
