OpenSpec 1.15 ships standalone binaries, so the spec-driven workflow no longer needs Node.js
Released Oct 24, every OpenSpec release now ships macOS, Linux (glibc and musl) and Windows binaries for x64 and arm64 with SHA256SUMS, installable with a one-line curl ... | sh script, which helps in CI runners and agent sandboxes without Node. It also adds openspec update --dry-run (with --json) to preview file changes before writing anything.
