Macos Windows Version Stamp

macOS and Windows binaries report the correct release version

The v1.0.4 macOS and Windows release binaries reported terragrunt version main and parsed as 0.0.0, breaking any terragrunt_version_constraint configured against them.

sign-macos.yml and sign-windows.yml included build jobs for standalone workflow_dispatch runs. During the release workflow, those jobs still saw the original workflow_dispatch event from release.yml, so the old condition evaluated to true. The redundant build used BUILD_VERSION=${{ github.ref_name }} and replaced the correctly versioned artifact uploaded by build.yml.

The signing workflows now skip their internal build job when invoked via workflow_call and only build when dispatched directly, so release binaries keep the version stamped by build.yml.
