Verified end-to-end with a full local build of all 8 packages on the actual runner host (docker exec against vbatts/slackware:15.0, bind- mounted repo on the cache pool) instead of round-tripping through Gitea Actions for each fix — much faster for a chain of issues this deep. All 8 packages now build successfully from a clean checkout. Three fixes, all in crun (the last package still failing): 1. "Package requirements (json-c >= 0.14) were not met" — added json-c to the toolchain bootstrap. 2. crun depends on the libocispec git submodule, which in turn depends on the image-spec and runtime-spec git submodules. GitHub's source archive tarball never includes submodule content (no .git directory for `git submodule update` to work against — the existing `|| true` masked this failing silently). Fetched all three as their own pinned tarballs instead, at the exact commits crun 1.28 references (cross-checked via the GitHub contents API), matching how every other dependency in this project is already pinned. 3. crun.c unconditionally #includes git-version.h, which crun's own Makefile only generates via `git describe` (again, no .git) or from a pre-existing .tarball-git-version.h — the file crun's own `make dist` would have written, which we never run. Write that file ourselves in the exact format the Makefile already expects; this is the documented fallback path bundled release tarballs rely on, not a workaround around it. Also includes the podman go-md2man pre-seed fix and setup-slackware- buildenv.sh python3 addition from the previous commit's follow-up testing (both already verified working in this same local build run).
