wassname d4ec550dd8 fix: corda silently ran as plain SVD; wire calibration + persist data-driven residual ...

The benchmark only passed calibration_data to eva, so antipasto_corda's
group_init hit `if calibration_data is None: return` and every corda run was
actually plain SVD. The covariance orientation never executed -- all prior
corda-vs-antipasto comparisons are void.

- antipasto_corda.group_init: raise on None instead of silently degrading
  (orientation is the variant's whole identity; fail loud).
- benchmark: feed ~256 MetaMath calibration samples (IPM, per PEFT/CorDA) to
  corda and to cov_orient ablate; run_id now carries an __lr tag.
- adapter.save/load: a data-driven group_init rewrites the frozen base residual
  W_res into a form init() cannot reproduce at load (it only knows the plain
  top-r crop). Persist those residuals in the adapter and restore them. Fixes a
  reload-logits mismatch that was masked while group_init never ran.
- probe check: compare every saved tensor (lora_ buffers AND base residuals)
  against the reloaded model state.
- justfile: bench-variant gains an lr_override (the core wants a tamer lr than
  the gain's 5e-3).
