- bench/bench.zig: 11 benchmarks (keccak, secp256k1, ABI encode/decode, RLP, tx serialization, HD wallet, EIP-712, address checksum) - build.zig: add `zig build bench` step (always ReleaseFast) - CONTRIBUTING.md: build/test/PR guidelines + architecture diagram - CHANGELOG.md: full v0.1.0 feature list - .github/ISSUE_TEMPLATE: bug report + feature request templates
