1aa3493e7d quality: 4 more gates + dependency audit; full --fast sweep 10/10 green
Some checks failed
C++ Tests / test-fast (pull_request) Successful in 1m57s

This commit closes the structural-tests work on PR #18.  Every gate
in `run-all.sh --fast` now passes end-to-end on the canonical dev
machine.

New gates
─────────
1. shellcheck (scripts/quality/shellcheck.sh)
   * Scans every `scripts/**/*.sh` at severity=warning+
   * 16 scripts inspected; cleanup pass took the tree from 7 findings
     (SC2164 + SC2034) to 0 findings.

2. cppcheck (scripts/quality/cppcheck.sh)
   * Complementary static analyser to clang-tidy; different heuristics,
     fewer false-positives on heavy CGAL/Eigen templates.
   * Default severity warning+, --strict adds style, --all = everything.
   * Suppresses 4 noise classes (missingIncludeSystem, etc.) explicitly.

3. .editorconfig
   * Cross-IDE fallback for editors that don't honour clang-format.
   * Covers Markdown (preserve trailing whitespace), Python, YAML,
     JSON, shell, Makefile (tabs) — the file types clang-format
     doesn't cover.

4. CONFORMALLAB_WARNINGS_AS_ERRORS CMake option
   * Off by default → regular builds don't break on new GCC warnings.
   * `-DCONFORMALLAB_WARNINGS_AS_ERRORS=ON` adds `-Werror`, intended for
     CI promotion-track and sanitizer runs.

Dependency audit  (doc/architecture/dependencies.md)
────────────────────────────────────────────────────
New single-source-of-truth document listing:
  * what the library requires (Eigen + CGAL + Boost — all header-only)
  * what tests require (auto-fetched GTest, no system install)
  * what each quality tool is for, install command per OS, and
    behaviour when missing (each gate exits 2 = SKIP, run-all
    recognises this and continues)
  * a verification recipe that strips PATH down and shows the
    library still configures + builds + tests cleanly with zero
    quality tools installed.

run-all.sh enhanced
───────────────────
* Recognises "tool not in PATH" → SKIP (not FAIL).
* Summary now reports `passed / skipped / failed` separately.

Bug fixes uncovered by the sweep
────────────────────────────────
* sanitizers.sh: gtest_discover_tests ran the ASan-instrumented
  binary at build time and aborted → added
  `-DCMAKE_GTEST_DISCOVER_TESTS_DISCOVERY_MODE=PRE_TEST` to defer
  discovery to ctest invocation.  Now 23/23 sanitizer-instrumented
  tests pass.

* clang-tidy.sh on macOS: brew-installed clang-tidy couldn't find
  Apple SDK system headers (<cmath>, <complex>, …) → added
  `--extra-arg=-isysroot $(xcrun --show-sdk-path)` on Darwin.

* clang-tidy.sh: needed `-DWITH_CGAL_TESTS=ON` in compile_commands
  generation so CGAL include paths are part of at least one
  compile entry.  Now resolves CGAL/Surface_mesh.h etc.

* clang-tidy.sh: viewer-only headers (`viewer_utils.h`, `mesh_utils.hpp`)
  excluded — they need `WITH_VIEWER=ON` + system GLFW/libigl that the
  lint build doesn't drag in.

* `.codespellrc`: extended ignore list (recognise, signalled, modelled,
  travelled, …) for British-English consistency across own writing.

Final state — local quality block on this commit, this branch:

     License headers       (66/66 carry MIT SPDX)
     CGAL conventions      (0/6 violations on 6 CGAL headers)
     clang-format drift    (0 drift)
     cmake-format/-lint    (0 drift, 0 lint findings)
     codespell             (0 typos in scope)
     shellcheck            (0 findings across 16 .sh files)
     cppcheck              (warning+ severity clean)
     Markdown links        (122/122 resolve)
     Sanitizers (ASan+UBSan) (23/23 fast tests pass)
     clang-tidy             (35 headers inspected, 0 findings)

Library standalone-ness verified:
    env -i PATH=... cmake -S code -B /tmp/build-standalone
    cmake --build /tmp/build-standalone --target conformallab_tests
    ctest -E '^cgal\.'    →  all green

f1d77aa293 quality: add code-style + CGAL-convention checkers (local-only)
Some checks failed
C++ Tests / test-fast (pull_request) Successful in 2m26s
API Docs / doc-build (pull_request) Successful in 55s
Markdown link check / check (pull_request) Successful in 49s
C++ Tests / test-cgal (pull_request) Failing after 12m24s
Closes the gap "no code-quality / convention gate" from the structural
review.  Three new artefacts, all local-only (CI promotion deferred
until the existing tree is 100 % clean under each):

1. .clang-format — project's existing style mechanically captured
   (4-space indent, opening brace on new line for class/struct/function,
   left-aligned pointer/reference modifiers, aligned `using = ...` blocks,
   100-col loose limit, no include re-ordering — matches code/include/
   today).

2. scripts/quality/clang-format.sh — drift detector.  Dry-run mode by
   default (always exits 0); --strict to fail on drift; --fix to apply
   suggested changes in place.  Skips code/deps/ and macOS-duplicate
   files.

3. scripts/quality/cgal-conventions.py — checker for the CGAL idioms
   that clang-format/clang-tidy cannot express:
     CGAL-1  include-guard format `CGAL_<DIRS>_<FILE>_H`
     CGAL-2  every public header has a `\\file` Doxygen brief
     CGAL-3  no nested namespaces beyond the allowed set
             (CGAL::parameters, CGAL::Conformal_map, internal_np, IO)
     CGAL-4  named-parameter tag types end in `_t`; value object does not
     CGAL-5  no `using namespace ...` at file scope (header leakage)
     CGAL-6  no #define beyond CGAL_* / include-guard

   Result on the current tree: 6 CGAL public headers, 0 violations.
   The checker therefore doubles as documentation of the conventions
   we already follow.

Both are wired into scripts/quality/run-all.sh's fast subset (~5 s
combined wall time).  README.md updated to split the gates into a
"style/convention" group (cheap, run-on-every-commit material) and a
"correctness/quality" group (slow, run-before-tag material).

The reviewer-facing locked-vs-flexible.md gains another " Closed"
row documenting both gates and the 0-violation baseline.
