negentropy-kmp v1.0.2 now publishes a macosArm64 artifact, unblocking
the macOS native target. Wired macosMain/macosTest source sets through
appleMain/appleTest and updated run_all.sh to run the K/Native
benchmark on both Linux (linuxX64) and macOS (macosArm64).

macosArm64 target cannot be enabled until negentropy-kmp publishes a
macosArm64 artifact — commented out with explanation. Reverted run_all.sh
back to Linux-only for K/Native benchmark.
Added Kotlin/Native toolchain dependencies (GCC sysroot, LLDB, LLVM,
libffi) to session-start.sh so K/N compilation works in Claude Code
remote environments where Gradle's own downloader fails through the
proxy.

- Declare macosX64() and macosArm64() KMP targets in build.gradle.kts
- Wire macosMain/macosTest source sets through appleMain/appleTest
- Move Secp256k1NativeBenchmark from linuxX64Test to nativeTest so it
runs on all native targets (Linux, macOS, iOS)
- Use platform() for dynamic labels instead of hardcoded "linuxX64"
- Update run_all.sh to pick the correct native target per OS/arch

Three issues fixed:
- Replace fragile -newer comparison against the script file (breaks
after any script edit) with a timestamp file created just before the
Gradle task runs.
- Search connected_android_test_additional_output for pulled benchmark
JSON (where AndroidX Benchmark actually writes results via Gradle).
- Extract benchmark data from XML via CDATA parsing instead of dumping
raw XML, consistent with the JVM and K/Native sections.

The ACINQ secp256k1-kmp-jni dylib ships with a relative LC_ID_DYLIB
("build/darwin/libsecp256k1-jni.dylib"). macOS dyld resolves this
literally, ignoring the -Wl,-rpath passed at link time, causing an
immediate abort at launch. Using install_name_tool to rewrite the
install name to @rpath/libsecp256k1-jni.dylib lets dyld find the
library via the rpath we already set.

The script was hardcoded for Linux (searching for .so files and
linux-x86_64 paths). Add platform detection via uname so it finds
the correct native library on macOS (darwin .dylib) and Linux
(aarch64 and x86_64). Skip K/Native benchmark on non-Linux since
only linuxX64 target exists.

run_all.sh runs all secp256k1 benchmarks and produces a formatted
comparison table. Runs C native, Kotlin/Native, JVM (always), and
Android (only if device/emulator connected via adb).
Output includes:
- ops/sec with comma-separated numbers
- libsecp256k1 vs Quartz column headers
- verifySchnorrFast and signSchnorr (cached pk) as Quartz-only rows
- Ratio table: C vs K/Native, JNI vs JVM Kotlin (apples-to-apples)
- Android column and ratios when device is connected
Run from repo root: ./quartz/benchmarks/run_all.sh

Standalone C program that links against the ACINQ secp256k1-kmp-jni
.so to benchmark raw C libsecp256k1 performance without any JVM, JNI,
or ART overhead. Uses the same test vectors as the Kotlin benchmarks.
Useful as a baseline when comparing Kotlin/Native or Android results
against the C library on the same hardware.
