verify_P019.py -- Paper 19: unified field equation synthesis.

This verifier checks the concrete arithmetic and proof-status claims in
toe/19_Paper_UnifiedFieldEquation.tex. P19 mostly synthesizes P18/P20-style
claims, so the verifier separates reproducible coefficient arithmetic from
claims that the standard Schrodinger, Dirac, Yang-Mills, and Einstein equations
are actually derived from the UFE in this TeX.

The basic constants reproduce: alpha=1/mu0, gamma=3/4, kappa=alpha^(5/4),
beta=3pi/20, the Planck-log formula, beta_geom=mu1/mu0, and the 3/11
dimension-ratio Weinberg estimate. The flagged issues are status/formula
problems: several coupling estimates are heuristic or dimensionally incomplete,
the cosmological-constant scaling does not give 1e-122 by itself, the beta
origin table is inconsistent with the standard B4 volume, and the four field
equation reductions are schematic rather than derived.
