/**
 * Returns the lexicographically-latest Prisma migration directory name
 * under `prismaRoot` (e.g. `"20260201000000_add_users"`). Lexicographic
 * order equals chronological order because of the fixed-width timestamp.
 *
 * Synchronous I/O — safe at both CDK synth time (the original use site) and
 * inside the migration runner script (the new use site). Throws when the
 * directory contains no entries matching `PRISMA_MIGRATION_DIR_RE`.
