/**
 * Extract Uniswap V1/V2/V3 swap events from a call trace. Pre-order walk,
 * skipping reverted subtrees. Logs that look like a swap-shape topic count
 * but don't match a known event hash are ignored (their `logIndex` still
 * increments so positions stay consistent with the on-chain receipt log
 * order).
 *
 * Variants are returned in a discriminated union — branch on `variant`.
 * V2-fork pools (SushiSwap, PancakeSwap V1, etc.) emit the same topic and
 * shape as UniV2 so they're decoded transparently. V4 hook-style pools
 * are not yet supported.
