fix(2): ghost BACKUP_VERIFY — drop __file__ (recipe_meta is exec'd, no __file__); import harness directly

full9: backup tier FAILed with NameError('__file__' not defined) — recipe_meta.py is exec()'d into a
bare namespace so __file__ is undefined. The harness already has runner/ on sys.path + harness imported,
so import lifecycle directly. (restore PASSED on full9 — the data-integrity fix works; this just fixes
the verify probe crashing the backup tier.)

     Returning False makes the harness re-run the whole backup with a re-stabilised db (run_recipe_ci
     _perform_op). It is a READ-ONLY probe — it weakens no assertion; it only retries a flaky CAPTURE."""
