Robust variance estimation in the browser: validation of allmeta rve-meta against robumeta and clubSandwich

Validation archive for the allmeta rve-meta page (engine shared/rve.js + shared/stats-qt.js) against robumeta 2.1 robu(modelweights="CORR", small=TRUE) and clubSandwich 0.7.0 coef_test(vcov="CR2", test="Satterthwaite") in R 4.6.0 on 16,270 configurations. Page as committed on allmeta branch fix/rve-meta-cr2-parity-p15-v2, commit e042af5 (draft PR #146). allmeta release: [ALLMETA RELEASE PENDING]; allmeta release DOI: [ALLMETA RELEASE PENDING]. The documented strict result is not full strict agreement: 785 configurations fail the 1e-9 criterion, each with a recorded diagnosis. Version 1.1 adds the merged engine (allmeta main 575cb29, PR #210; release v1.9.0, DOI 10.5281/zenodo.23833871): 16,136 of 16,270 configurations at 1e-9 under the finite-only rule and 16,221 under Option A, where both-undefined agrees only for the same reason (85 configurations).
