/**
 * run-check.mjs — aggregate quality check runner (M1, S-106)
 *
 * Runs every quality gate in sequence and reports a summary.
 * All steps run even if earlier steps fail, so you get a complete
 * picture of the repository health in one pass.
 *
 * Transitional contract (M1):
 *   This script may exit non-zero.  Pre-existing failures are recorded in
 *   docs/CLEANUP-BASELINE.md.  Only issues introduced by new changes (not
 *   listed in the baseline) constitute a regression.
 *
 * Usage:
 *   node scripts/lib/run-check.mjs          # full check
 *   pnpm run check                           # same, via pnpm
