- Add setup.sh (Unix) and setup.bat (Windows) build scripts that detect
platform, check dependencies, and build all components (JS, WASM, miner)
- Add GitHub Actions CI workflow (test on push/PR)
- Add GitHub Actions release workflow that builds static miner binaries
for Linux x86_64/aarch64, macOS Intel/Apple Silicon, and Windows
- Switch miner from OpenSSL to rustls for zero runtime dependencies
- Fix wallet-sync batch fetching (remove broken .bin binary endpoint,
use sequential JSON-RPC get_block calls)
- Add portable storage binary format serializer/deserializer for future
batch RPC support
- Add postBinary() to RPC client for binary endpoint communication
- Update package.json: bun-only runtime, remove node/npm references
