/**
 * Sync pkg/package.json version with the installed @mariozechner/pi-coding-agent version.
 *
 * sf-run sets PI_PACKAGE_DIR=pkg/ so that pi's config.js reads piConfig from
 * pkg/package.json (for branding: name="sf", configDir=".sf"). However, config.js
 * also reads `version` from that same file and uses it for the update check
 * (comparing against npm registry). If pkg/package.json has a stale version,
 * pi's update banner fires even when the user is already on the latest release.
 *
 * This script reads the actual installed pi-coding-agent version and writes it
 * into pkg/package.json so VERSION is always correct at publish time.
