feat(regression): add E2E canary regression suite (tests/regression/)
Seven canaries prove both halves of the server's job:
- GREEN: good apps are reported healthy (good-simple + good-significant)
- RED: broken apps are caught at intended tier (false-green guard + 4 per-tier)

Fixtures: custom-html-bkp-bad (backup tier RED) + custom-html-rst-bad (restore tier RED).
All 7 canaries verified on live server (see STATUS-regression.md for artifacts).

Not wired to per-commit CI — run on-demand: pytest -m canary tests/regression/

"""custom-html-bkp-bad — BACKUP assertion (bad-backup RED canary).
This recipe has no ops.py::pre_backup, so ci-marker.txt is NEVER seeded before the backup.
Asserting its presence here causes backup tier RED — proving the server catches a recipe that
claims backup support but doesn't actually back up the expected data.
