Add tools/test_fut_contract.py -- stdlib-only, read-only tests that hit the live
utas_server and assert each response matches the shape reversed from CardsDLL
(docs/ENDPOINT_MAP.md). Encodes freeze-safety invariants (auctionInfo/players/
itemData/currencies/purchase must be array/object per the SAX deserializers;
scalar-where-container = busy-loop freeze at 0x1801c7f1a) plus the specific
contracts: v2/store gate == SUCCESS, coin counter binds currencies[coins].funds,
userMassInfo stays {}, empty squad slots carry itemData=null (proven-safe).
Catches the regression class that previously bit us (phantom packs, coins-0,
squad reset). 58 checks, all passing.
