…ksum parsing - Switch getLatestVersion to GitHub REST API JSON response instead of redirect parsing - Replace identity maps in getBinaryAssetName with Set-based validation - Parse checksum line once and reuse; compute Buffer.from(binary) once
ky sends the runtime's default User-Agent automatically; GitHub only rejects requests with an empty header, not a missing one.
Single-use method with no reuse benefit; inlining reduces indirection.
Fetch checksums before the binary to validate platform support dynamically instead of hardcoding allowed platforms/archs.
Both npm and binary paths now run automatically. Removes the manual_update_required status — all updates return status: updated.
