# Snapshot the Copilot CLI version + per-platform SHA-256 hashes for the

# rust crate's bundled-CLI build.rs. Runs at SDK publish time, mirroring

# how .NET's _GenerateVersionProps BeforeTargets="Pack" target writes

# GitHub.Copilot.SDK.props before NuGet packing.

#

# Inputs:

# - ../nodejs/package-lock.json (sibling) - source of the pinned version.

# - https://github.com/github/copilot-cli/releases/v{version}/SHA256SUMS.txt -

# authoritative per-platform hashes.

#

# Output:

# - cli-version.txt (in the rust crate root). Gitignored.
