deer-flow/scripts/bump_version.sh

#!/usr/bin/env bash
# Bump the project version across every version source in lockstep.
#
# Usage:
#   scripts/bump_version.sh <version>     # e.g. scripts/bump_version.sh 2.2.0
#
# Updates:
#   backend/pyproject.toml              (version = "...")
#   frontend/package.json               ("version": "...")
#   deploy/helm/deer-flow/Chart.yaml    (version: + appVersion:)
#
# This does NOT edit CHANGELOG.md or create/push a git tag — keep those manual.
# After running, commit and tag v<version> to trigger the release workflows
# (container.yaml + chart.yaml), which gate on scripts/verify_versions.sh.
