// Assemble builds the full P6 background-reconcile Runner: order-expire /
// usage-refresh / refund-apply-sweep / refund-stuck-alert (local, DB-only,
// AddLocal — run synchronously once at startup by main.go's RunOnceLocal) +
// sync-pending / paid-spotcheck (network, Add — first tick handles it) +
// crypto warm(直跑)+ crypto-orphan-scan(AddCryptoJobs,network,只在 crypto 渠道
// 已注册时挂载).
//
// 抽出这个函数纯粹是为了让"预期任务集合是否都注册上"能被直接单测(main.go 原先把
// 这段写死在 main() 里,main() 本身因为要拉真实 DB/HTTP server 不适合单测——见
// assembly_test.go)。main.go 对应 `if config.C.Reconcile.Enabled` 分支现在只是薄薄
// 一层:调这里 + RunOnceLocal/Start/日志,行为与抽取前逐行一致,未改任何调度语义。
