/**
 * Extract ERC-20 Transfer events from a call trace. Walks the tree depth-first
 * and collects logs attached to each frame (populated by `withLog: true`
 * callTracer mode). Reverted call frames and their entire subtrees are
 * skipped — those logs are rolled back on-chain and would not appear in the
 * transaction receipt.
 *
 * ERC-721 Transfer events share the same topic hash but have 4 topics
 * (tokenId is indexed); they are filtered out. ERC-1155 transfers use
 * different topic hashes and are not decoded here.
 *
 * Returns an empty array if the trace contains no logs or no Transfer events.
 * `logIndex` reflects the position within the *successful* log stream
 * (matching what a receipt would contain), not the raw walk order.
