ci: fix test-cgal OOM + add Doxygen API-docs job
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.
