variants: clean docstrings to research pseudocode; arrow block param

Browse Source 
Rewrite antipasto/ablate/corda/arrow docstrings to the house style (purpose +
math block + identity line + refs), dropping the rambly meta-commentary aimed at
past design decisions ('Changes vs the rotation version', chat references, inline
measurements). Net -74 lines.

Also answer the FIXMEs left on main's old copy:
  - group_init is Wanda/ASVD *selection* (re-rank W's own singular vectors), NOT
    CorDA re-orientation -- that is antipasto_corda.py.
  - it rebuilds the FULL W exactly (W_res + stored top-r == W), so the re-SVD sees
    the whole spectrum, not a cropped matrix.

Arrow capacity: --antipasto-block CLI knob (justfile bench-variant 4th arg) so the
block can be scaled toward LoRA params; run_id gets a __b<N> suffix so block-sweep
runs do not collide. Smoke green (14 passed).
