- Split all p8k files into *_linux.go and *_other.go variants
- Linux files use purego to load libsecp256k1.so dynamically
- Other platforms (darwin, windows, android, js/wasm) use stub that
forces fallback to pure Go p256k1.mleku.dev implementation
- Add !android to Linux build tags since Android matches linux but
purego requires CGO on Android
- Extract shared constants to constants.go (no build tags)
- Enables cross-compilation for macOS, Windows, and Android without
requiring libsecp256k1 or CGO
Build tags:
- Linux: //go:build linux && !android && !purego
- Other: //go:build !linux || android || purego
