Research direction

Start by reproducing the failure from BcosSDKTest.main at BcosSDK.build(path), then trace the stack through BcosSDK, CryptoSuite, ECDSAKeyPair.java:66, and NativeInterface.secp256k1GenKeyPair. Compare the 2.7.2 and 2.8.0 native crypto dependencies or loading behavior. Done means version 2.8.0 initializes without UnsatisfiedLinkError and can connect to the chain node.
