bump-version.sh

#!/usr/bin/env bash
#
# Single source of truth for the project version.
#
# The workspace version in the root Cargo.toml ([workspace.package] version) is
# authoritative. The Tauri app derives its version from it (tauri.conf.json has
# no `version` key, so Tauri falls back to CARGO_PKG_VERSION), which is what the
# installers, bundle metadata and the in-app About screen (getVersion()) show.
#
# This script keeps the remaining, non-derivable copies in lockstep:
#   * root Cargo.toml      — the source value
#   * Cargo.lock           — workspace member entries
#   * app/package.json     — npm metadata
#   * app/package-lock.json
#
# Usage:
#   scripts/bump-version.sh <X.Y.Z>
#
# After it runs, review `git diff`, then commit and tag, e.g.:
#   git commit -am "release: vX.Y.Z" && git tag -a vX.Y.Z -m "release: vX.Y.Z"
#   git push origin main && git push origin vX.Y.Z   # the tag triggers the release workflow

# 2) npm metadata: npm rewrites both package.json and package-lock.json
#    consistently. --no-git-tag-version keeps git untouched; --allow-same-version
#    makes re-runs idempotent.

# 3) Cargo.lock: refresh the workspace member version entries from Cargo.toml.
