fix(evolve-lite): roll back subscribe clone when audit append fails

Subscribe now treats audit_append failure as fatal: pop the repos entry,
re-save the config, remove the cloned directory, and exit non-zero —
matching the existing save_config rollback path. This restores the
contract asserted by test_rolls_back_clone_if_audit_write_fails for
both the claude and codex subscribe variants.
