fix: build hashes and recovery-phrase entropy come from ethers (closes #758 )

build.js and script/lib/package.js hash with sha256 from ethers, with the 0x prefix stripped so the build receipt and SHA256SUMS keep bare lowercase hex. generateMnemonic() takes its 16 bytes of entropy from randomBytes in ethers. The README Crypto policy no longer lists these as exceptions. Model: opus-5-5
