getItem
suspend fun getItem(target: Sha1Hash, mutableSeq: Long? = null, maxRounds: Int = 12): DhtNode.GetItemResult
Fetch a BEP-44 item from the DHT. This is the client port of node::get_item and its traversal. Runs a get traversal toward target, merging closer nodes from each reply, and returns the best item found (the highest-seq verified mutable item, or the immutable item) together with the closest responders and their write tokens (so a follow-up putItem can re-publish without a second lookup).
Parameters
mutableSeq
if non-null, an optional seq hint to add to the query so peers may withhold a value the caller already has.
