Add dev-ghost-doctor.sh (t-shadow check + runtime clean + restart) and
dev-ultra-restore.sh (deep clean with --full/--no-start/--check flags).
Improve check-no-t-shadow.sh patterns for broader t-variable detection.
Clean-dev-runtime now runs guardrail check automatically. Remove --force
from vite dev. Add npm script shortcuts for all new tools.
