The custom C secp256k1 implementation under quartz/src/main/c/ was never
wired into Gradle (no externalNativeBuild block) and only existed for the
3-way benchmark + cross-validation test against ACINQ on JVM/Android.
The C library has been split out to vitorpamplona/libschnorr256k1{,-kmp},
so the in-repo copy is dead weight.
This change replaces it with the published Maven Central artifact
`com.vitorpamplona:schnorr256k1-kmp:1.0.0`, scoped to test/benchmark
configurations only — production crypto continues to use ACINQ
secp256k1-kmp on JVM/Android and the pure-Kotlin Secp256k1 on native.
The Android AAR ships libschnorr256k1_jni.so for arm64-v8a and x86_64,
so the Android benchmark now exercises the C row automatically (no more
manual build_android.sh). On JVM the .so still has to be installed by the
developer; the cross-validation test and triple-benchmark gracefully skip
the C row when System.loadLibrary fails, matching prior behavior.
Verified on JVM: all 13 secp256k1 jvmTest classes pass (188 tests), and
ACINQ vs pure-Kotlin benchmark numbers match the documented baseline
within sandbox noise (verifySchnorr ~15k ops/s, signSchnorr cached
~33k ops/s, pubkeyCreate+Compress ~36k ops/s).
Removes ~5,100 LOC: quartz/src/main/c/ (4,500), Secp256k1InstanceC.*
expect/actual shim (560), Secp256k1C JNI declaration object.
