set-date-version.mjs

#!/usr/bin/env node
/**
 * Set package.json version to a CalVer YYYY.M.D (no leading zeros) based on UTC date.
 * If the current version already matches today's date, append a numeric suffix
 * (YYYY.M.D.N) to keep publishing multiple builds per day — npm accepts 4-segment
 * versions via the semver "build" via prerelease style is not ideal, so we instead
 * go to YYYY.M.D{N*10+...} style — but most of the time this is a no-op.
 *
 * Convention matches AceDataCloud MCP servers (e.g. SunoMCP: 2026.1.22, 2026.1.22.6).
 *
 * Usage:
 *   node scripts/set-date-version.mjs            # set to today's date
 *   node scripts/set-date-version.mjs --dry-run  # print only
