Gitea Actions on GHES does not support actions/upload-artifact@v4 — the
v4 release switched to GitHub-only APIs (artifact backend rewritten).
The doc-build job was failing with "artifact@v4+ are not currently
supported on GHES."
Changes
───────
* Removed the artifact-upload step entirely. Rationale: the warning
summary in the job log is the primary reviewer signal for the
documentation health check. Reviewers who want to inspect the HTML
locally can rebuild it with `cmake --build build --target doc`.
* Removed the apt-get install step. Doxygen is now pre-installed in
the ci-cpp container (Dockerfile change earlier in this PR).
* Added an explanatory comment so the missing artifact step is not
re-introduced unknowingly.
* Added a "Report HTML output" step that prints file count + total size
for visibility (a no-op if the HTML directory is absent).
When/if a real artifact host appears (Gitea Pages, S3, GitHub mirror
release), this job can be extended to publish the HTML there. For now,
the in-log warning summary is sufficient.

Two CI improvements:
1. **test-cgal OOM fix**
* memory limit 1400m → 1600m (cc1plus needs ~700 MB for CGAL + Eigen)
* memory-swap 1400m → 1600m (was less than memory, Docker rejected
the config; now disables swap entirely
so OOM fails fast)
* build parallelism -j2 → -j1 (single worker leaves headroom)
These three changes together address the test-cgal failures observed
since the test_scalability_smoke.cpp was added. Locally the full
suite (183 tests including the brezel.obj genus-2 mesh) runs in
~1 s with peak ~700 MB; the ARM64 CI runner now has the same
headroom.
2. **API-docs job (new, soft-fail)**
* .gitea/workflows/doc-build.yaml — separate workflow, distinct name
"API Docs"
* Runs only on pull requests; `continue-on-error: true` ensures
warnings never block the merge
* Installs doxygen, runs `doxygen Doxyfile`, uploads the generated
HTML as a 14-day artifact for reviewer inspection
* Dockerfile.ci-cpp also pre-installs doxygen so future iterations
can drop the in-job install step
When Doxygen coverage matures (Phase 8c — User_manual.md), this job
can be promoted to a hard requirement and the HTML deployed to
Pages.
