chore: add Redis/PgBouncer readiness checks to setup.sh + post-change checklist rule to CLAUDE.md

setup.sh now waits for Redis PONG and PgBouncer pg_isready before running
Prisma migrations. CLAUDE.md gets mandatory post-change checklist ensuring
setup.sh, README.md, PROMPT.md, .env.example stay in sync after every change.
