ci+licenses: promote 4 trivial gates to required CI + third-party license doc
Two reviewer-facing additions:

1. New `quality-gates` job in .gitea/workflows/cpp-tests.yml
   ──────────────────────────────────────────────────────────
   Runs in parallel with test-cgal after test-fast.  Installs
   `codespell` + `shellcheck` (apt) into the existing ci-cpp container,
   then executes four scripts strictly (exit 1 on any finding):
     * license-headers.sh   — 66/66 files carry SPDX MIT
     * cgal-conventions.py  — 0 violations across 6 CGAL public headers
     * codespell.sh         — 0 typos across docs + source + scripts
     * shellcheck.sh        — 0 findings across 16 shell scripts

   Each ran at 0 findings locally for weeks before promotion.  The
   gates are now contractual: a regression fails the PR.  Total
   wall-time on the eulernest runner: ~30 s.

2. New code/deps/THIRD-PARTY-LICENSES.md
   ──────────────────────────────────────
   Enumerates every vendored dependency under code/deps/, plus the
   auto-fetched GoogleTest, plus the system-required Boost, with:
     * upstream project + version + SPDX identifier
     * compatibility note for MIT distribution
     * a downstream-packager license matrix (header-only consumer
       vs CLI binary) clarifying the LGPL §3 vs §4 distinction
       relevant to CGAL's header-only consumption

   Required for any future Linux-distribution packaging and for the
   CGAL submission's compliance check.  Cross-referenced from
   doc/architecture/dependencies.md.

# Run shellcheck across every Bash script we own (scripts/**/*.sh).

# Local-only. CI promotion once every script is shellcheck-clean.

# Usage:
# bash scripts/quality/shellcheck.sh # warn + advisory exit 0
# bash scripts/quality/shellcheck.sh --strict # fail on any finding

# Exit codes:
# 0 no findings, or findings but --strict not set
# 1 --strict was set and shellcheck reported findings
