Tom Boucher 697cbb1f05 test(#1977): consolidate 22 misc + repo-invariant regression tests
Final epic-#1969 batch. Fold 22 issue-named files: the 4 genuine repo-wide invariant
scans (551-eslint-bin-lib-coverage, bug-3054 stale /gsd-next, bug-3810 no-gsd-sdk-runtime-refs,
feat-3593 cli-negative-universal) into a NEW shared repo-invariants.test.cjs; the other 18 as
singletons into their nearest module suite (model-resolver, codex-config, runtime-converters,
security, state-transition, worktree-safety, roadmap-parser, etc.). Verbatim block-scoped
describe wrappers; 334 subtests conserved 1:1.

Host-env pre-check (B2+B6): the 6 CLI folds into GSD_TEST_MODE-setting hosts (model-resolver/
codex-config/runtime-converters) are benign — each origin independently sets GSD_TEST_MODE=1
itself (idempotent), unlike the B6 real-install case.

Regenerates regression-name allowlist (222->213), ratchets file-count allowlist (state 17->16),
makes 7 relocated allow-test-rule exemptions issue-ref-compliant (ADR-456; prunes stale ids).
Repoints 2 tests/ refs in docs/TESTING-SUITES.md. lint:ci green.

Part of epic #1969. Closes #1977.
