Packages and release artifacts

The SDK exports installed CMake targets under the a2a:: namespace. Use CMake integration or the repository-local vcpkg overlay to consume a reviewed release.

Release tags use v<major>.<minor>.<patch>. The release packaging workflow produces source .tar.gz and .zip archives and SHA256SUMS.txt on GitHub Releases. Verify the checksum after downloading. Pin source dependencies to a release tag or reviewed commit and keep generated protobuf headers and linked libraries from the same package or build tree.

The repository-local overlay is distinct from publication in the public microsoft/vcpkg registry. A local overlay does not prove registry availability. See release compatibility notes and supported versions before upgrading.
