v2.13.0

Changed

• 1inch now quotes through 1inch Fusion (intent mode) instead of 1inch Classic. Classic cannot route through pools that only admit allowlisted senders (it quoted a BSC DTF at ~84% price impact where Fusion quotes ~1%); Fusion orders are filled by resolvers that can. The provider id stays '1inch', so PROVIDER_ENABLED[chain]['1inch'] keeps working, and the Reserve API must serve the new /1inch/fusion/quote, /1inch/fusion/order and /1inch/fusion/order/{chainId}/{orderHash} routes (the widget no longer calls /1inch/swap). The order is built by the API, so the widget gains no dependency. The order that is signed or placed is re-quoted at click time (a Fusion auction starts seconds after the order is built), and the click is refused if the fresh floor is more than 0.1% below the displayed minimum. ERC-20 inputs sign a gasless order; native inputs (ETH/BNB) send one transaction to 1inch's native order factory and are refunded by 1inch resolvers if the order expires unfilled.
• For host apps: PROVIDERS['1inch'] is now kind: 'rfq' (buildEndpoint() returns null, no apiSlug, rfq holds the adapter), getEnabledAggregators() no longer lists 1inch,, isRfqProvider('1inch') is true and RFQ_ADAPTERS['1inch'] holds the adapter. ProviderId is unchanged.
• Tracking: the 1inch source in Quote Source Winner / Quote Source Picked now means Fusion, and it emits the RFQ order events (order_submitted, order_filled, order_expired, ...). Like every RFQ source, its quotes carry no transaction, so the pre-selection simulation filter and gas estimation do not apply to them.
