Record the matching battery: fifteen solvers, one amplifier

Adds MATCHING_RESULTS.md. Entropic GW annealed and PATH both reach 0.961
on the reference field, above the 0.958 the project's own pipeline
reached after months, and neither had been run. GW reaches 0.881 on the
rank-8 field where GRAMPA reaches 0.076 -- which retires the morning's
rank-ladder conclusion, since that ladder was run entirely with GRAMPA
and GRAMPA degrades on clustered eigenvalues.

The hard instance yields to amplification rather than a better solver:
descent multiplies a partial answer by about four, so the job is to feed
it a start that is 10-20% correct rather than to replace it.
