Max coin objects consolidated per transaction, and the cap on every per-type
coin-object read; callers re-run until one remains. Bound by transaction
size, not the 512-argument command limit: each coin is an owned-object input
costing ~79 serialized bytes, against a 16384 limit on the gasless
transaction. 180 measures ~14.3KB, leaving headroom for the gas coin and
address-balance withdrawal the SUI paths add on top.
