feat(1e): HC3 additive generic + op/assertion split (orchestrator owns the op)

- orchestrator: per mutating tier, run optional pre-op seed hook (ops.py pre_<op>) → perform the op
  ONCE (harness-owned) → run generic assertion (unless opted out) AND overlay assertion, both against
  the shared post-op deployment. Op results passed op→assertion via run-scoped CCCI_OP_STATE_FILE.
- opt-out: CCCI_SKIP_GENERIC / CCCI_SKIP_GENERIC_<OP> / recipe_meta.SKIP_GENERIC (declarative).
- generic.py: split do_* into op primitives (perform_upgrade/backup/restore) + assertions
  (assert_upgraded/backup_artifact/restore_healthy) reading op_state(); deployed_identity now returns
  {version,image,chaos} (chaos label ready for HC1).
- generic test_<op>.py + all 6 recipe overlays migrated to assertion-only; pre-op seeding moved to
  per-recipe ops.py (pre_upgrade/pre_backup/pre_restore). install overlays unchanged (no op).
- deploy-count stays 1 (op primitives never call deploy_app). lint PASS; 8 unit tests PASS on cc-ci.
