Since M10-C. estimateFee implements a HardKAS "conservative"
+10% heuristic over the pinned SDK mass, on top of a hardcoded
DEFAULT_MINIMUM_RELAY_RATE_SOMPI_PER_MASS = 100n. Upstream
Generator.estimate() (via estimateTransactionsUpstream in
kaspa-wallet-adapter.ts) is exact — no +10% padding, and it reads the
network params from the SDK. Use that for anything you plan to submit.
This function will continue to work through M10 for backward compatibility but SHOULD NOT be used in new code.
