Tarik Moussa 0f78d181e1 docs: centralise test counts + add release-policy + remove stale stub references
Two complementary improvements aimed at reducing recurring maintenance
overhead:

1. **Test-count centralisation** — `doc/api/tests.md` is now the
   single source of truth for the test counts.  All other docs
   (README, CLAUDE.md, doc/contributing.md, doc/getting-started.md,
   doc/math/validation.md, doc/math/validation-protocol.md,
   scripts/try_it.sh) use qualitative phrasing + a link instead of
   hardcoded numbers.  The previous regime had eight places with
   "227 CGAL tests, 23 non-CGAL tests" that drifted apart across
   releases (the v0.9.0 release-prep needed to touch nine files).

2. **Versioning policy** — `doc/release-policy.md` (new, ~250 lines)
   formalises:
   * SemVer rules for the pre-1.0 and post-1.0 phases.
   * Phase-milestone → MINOR-bump mapping (v0.10.0 → Phase 9c, …).
   * Single-source-of-truth table for moving numbers (test counts,
     version, date).
   * Step-by-step release process (the recipe that worked for v0.9.0
     after the false-start with PR #11/#12).
   * Hotfix policy + post-1.0 deprecation policy.
   * Known failure modes and how to recover from them.

Plus a small CI gate:

3. **scripts/check-test-counts.sh** — verifies the totals in
   doc/api/tests.md match `ctest` output.  Re-uses existing build-cgal/
   if present.  Exit 0 on match, 1 on divergence with recovery hints.
   Cheap enough (~30 s) to run on every PR.

Other cleanups
──────────────
* code/tests/cgal/CMakeLists.txt — stale "Test 7 (genus-2 homology)
  as GTEST_SKIP stub until Phase 8" comment removed; that test landed
  as HomologyGenerators.Genus2_FourCutEdges in Phase 7.
* CLAUDE.md — "test-fast also runs stubs" Known Quirks entry updated
  to reflect the v0.9.0 stub cleanup (no GTEST_SKIPs remain).
* CLAUDE.md doc map — new entry for doc/release-policy.md.

Stubs audit
───────────
Zero GTEST_SKIP() calls remain in the codebase as of this commit.
The only references to stubs are in historical documentation
(CHANGELOG.md v0.7.0 entry, doc/roadmap/* "deferred to research-track"
notes) — those are intended.

# Contributing
## Language
**All code, comments, documentation, commit messages, and test descriptions must be in English.**
The project targets CGAL submission and international collaboration. When editing
files that still contain German-language comments or documentation, replace them
with English.
---
## Git workflow
- `main` is protected on `origin` (Gitea). Push to `dev`, then open a pull request.
- `codeberg/main` can be pushed to directly (public mirror, no CI).
- Both remotes must stay in sync after every significant change:
```bash
git push origin HEAD:dev # triggers CI
git push codeberg main # updates public mirror
```
- Branch naming: `feature/<topic>`, `fix/<topic>`, `phase<N>-<topic>`
---
## CI
Two jobs run on push to `dev`/`main` or on pull requests:
| Job | What it tests | Trigger |
|---|---|---|
| `test-fast` | pure-math tests, no Boost | all branches |
| `test-cgal` | full CGAL test suite | `main`, `dev`, PRs only |
A PR is ready to merge when both jobs pass.
The runner is a self-hosted Raspberry Pi (ARM64). See `.gitea/workflows/cpp-tests.yml`
and `.gitea/docker/Dockerfile.ci-cpp`.
---
## Test standards
Every new algorithm needs:
1. **Gradient check** — finite-difference verification of `G(x) = ∂E/∂x`.
Copy any `GradientCheck_*` test suite from `tests/cgal/test_*_functional.cpp`.
2. **Convergence test** — Newton converges on a small mesh using the "natural theta"
trick (see [CLAUDE.md](../CLAUDE.md) and [api/extending.md](api/extending.md)).
3. **Registration** — add the `.cpp` file to `code/tests/cgal/CMakeLists.txt`.
Expected CI result: full test suite passing, 0 skipped (per-suite counts: [`doc/api/tests.md`](api/tests.md)).
---
## Code style
- C++17. Header-only (`code/include/*.hpp`). No compiled library.
- `#pragma once` at the top of every header.
- Everything in the `conformallab` namespace, internal helpers in `conformallab::detail`.
- Property map names follow the prefix convention: `"v:"` (vertex), `"e:"` (edge), `"f:"` (face).
- DOF index `-1` always means "pinned/fixed".
---
## Releases
Release tags follow `vMAJOR.MINOR.PATCH`:
```bash
# Merge dev → main, then tag
git checkout main && git merge --no-ff dev
git tag -a vX.Y.Z -m "vX.Y.Z — <one-line summary>"
git push origin main && git push origin vX.Y.Z
git push codeberg main && git push codeberg vX.Y.Z
```

## TODO
- [ ] Define code review checklist
- [ ] Add `.clang-format` configuration
- [ ] Document how to request CGAL package review
