/**
 * Syncs the Git-marketplace catalog version with package.json.
 *
 * The marketplace (`.omp-plugin/marketplace.json`) serves the repo tip, and omp
 * uses the catalog `version` for upgrade comparisons. If it lags the published
 * package version, marketplace users are never offered new releases.
 *
 * This runs automatically as the npm `version` lifecycle script (`npm version`
 * → this → commit), so every release keeps the catalog in step. It rewrites
 * `metadata.version` and every `plugins[].version` to package.json's version and
 * stages the file so it lands in the same version commit.
 *
 * Idempotent: a no-op when already in sync (nothing to stage). Also runnable by
 * hand: `bun tools/sync-marketplace-version.ts`.
