# 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
#
# What it does:
#   1. Updates version in root package.json and package-lock.json (requires Node)
#   2. Commits the version bump
#   3. (optional) git push + push the new tag
#
# It does NOT:
#   - Build the Docker image (run `./scripts/build-image.sh`/`docker compose up -d --no-build` yourself
#     or wire it to a deploy script / CI hook)
#   - Touch anything Android. The Capacitor project and its APK build were
#     removed; if they come back, restore the version-bump lines from git
#     history along with them.
# ============================================================
