// 2026-03-20 (merge: sless_function + старый sless_job объединены в один self-contained sless_job)
// Теперь sless_job несёт в себе runtime/entrypoint/source_dir — не нужен отдельный sless_function.
// WaitJobDone таймаут 900s покрывает kaniko сборку (~5 мин) + выполнение SQL (~несколько сек).

# Одноразовый запуск: собирает образ через kaniko, выполняет SQL, завершается.
# Заменяет sless_function.postgres_sql_runner_create_table + sless_job.postgres_table_init_job.
