Server-side SwapExactInput preview. The swap_exact_in_quote FFI op orients the pool reserves to the requested in/out direction, prices via the shared amm_core::swap_exact_in_amounts (so expectedOut matches the chain), and derives the slippage floor: { expectedOutRaw, minReceivedRaw, priceImpactBps }. no_pool is returned as an error; pool metadata (reserves/fee) comes from resolve_pool, so it isn't echoed. Read-only — no quoteHash; the on-chain min_amount_out is the real guard.
The module swapExactInQuote(tokenIn, tokenOut, amountIn, slippageBps) method derives the pool via the config-free pool_id op, reads it, and wraps the op in the { status, error, ... } envelope; call() now surfaces the op error code so no_pool propagates.
The QML swap view still uses the old path, so nothing breaks. Will make the QML consume it in a follow-up.
