Three small cleanups surfaced by running the full gate sweep on the
merged main:
1. CGAL conventions (CGAL-2 \\file briefs)
doc-only headers `Conformal_map/doxygen_groups.h` and
`Conformal_map/doxygen_namespaces.h` were missing the `\\file`
brief required by the CGAL conventions check. Added both.
2. codespell — three new triggers
`code/tests/cgal/CMakeLists.txt` uses "honour", `doc/reviewer/hub.html`
uses `<thead>` (HTML tag, false-positive for "thread"), and
`doc/roadmap/research-track.md` uses "optimiser". All three are
British-English / HTML usage; added to `.codespellrc` ignore list.
3. Doxygen warning in `doc/architecture/compile-time.md:250`
A trailing backtick-quoted CMake flag at end-of-file confused
Doxygen's markdown parser into starting a never-closing verbatim
block. Rewrote the line to put the prose first and the backtick
in the middle, not at end-of-file.
All gates green again on the merged main:
✅ 259/259 tests pass
✅ test-count consistency
✅ markdown links 166/166 resolve
✅ CGAL conventions 0/8 violations
✅ license-headers 68/68 carry MIT SPDX
✅ codespell 0 typos
✅ shellcheck 0 findings (18 scripts)
✅ Doxygen 100% coverage, 0 warnings
