# Purpose: Update all lockstep version fields from one explicit input version.
# Key outputs: Rewrites crate, Python, Node, Node lockfile, and native crate versions.
# Role: Maintainer tool to reduce release-time manual edits and drift.
# Invariants: [package]/[project] version keys stay valid and synchronized.
# Notes: Runs alignment check at the end and exits non-zero on parse/update errors.
