# Bump the project version in EVERY file the release `version_sync` gate
# checks, in one shot, so a release can never fail because one copy was
# forgotten (the recurring SKILL.md drift that broke the 0.22.1 and 0.23.0
# tags). The version lives in two hand-maintained places — Cargo.toml's
# [package] version and SKILL.md's frontmatter — and they MUST agree with the
# release tag. Always bump via this script (or `just bump-version`) instead of
# hand-editing either file.
#
# Usage: scripts/bump-version.sh <X.Y.Z>
#
# After running: add a `## [vX.Y.Z]` section to CHANGELOG.md, commit, and tag
# `vX.Y.Z`. The release workflow's validate gate will then pass.
