Fresh clones are now fully self-contained / offline (no first-run fetch needed). Binaries (linux x64/arm64, darwin x64/arm64, win32 x64) tracked via LFS; verified against bin/checksums.txt. First-run release fetch kept as a no-lfs fallback. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
