Add a check that the shared library's ABI stays consistent with its version numbers, so an incompatible change cannot ship under an unchanged SOVERSION. The check compares the built library against an in-tree baseline of the last released ABI (captured with libabigail's abidw) using abidiff, classifying the result as an incompatible change, compatible additions, or no change. It then enforces the versioning policy: an incompatible change requires both SOVERSION and project VERSION to increase; compatible additions require a VERSION increase; no ABI change requires nothing. Because a minor version bump may carry an ABI break, SOVERSION rather than a semver major is the compatibility guard. The policy is a pure core, so the whole matrix is unit-tested with plain data without building anything; the shell around it gathers facts and renders. Classification reads no version data from CMakeLists.txt: SOVERSION comes from the built library's ELF SONAME and the version from its own mg_client_version(). An update subcommand refreshes the baseline, and optionally sets the CMake variables, on an intended ABI change or release. The check and the policy tests run as a new job on push and pull_request.
