feat(M11.2-M11.4): combine Liouville tensor, QDO interactions, and optional QCD

[jagg-ix]

Combined M11.2–M11.4

This PR consolidates the Liouville-tensor, QDO/Lennard–Jones/Axilrod–Teller, and optional QCD changes into one direct-to-main commit.

The earlier M11.2 PR was merged into the M11.1 feature branch rather than into main, so this combined PR carries the complete prerequisite chain after the already-merged M11.1 carrier.

M11.2 — Liouville soliton tensor

Constructs rho_ij = a_i conjugate(a_j) from the pointwise soliton in a centered Fourier-mode cutoff. It verifies Hermiticity, trace one, rank-one purity, positive semidefiniteness, commuting pointwise left/right actions, fixed finite particle number over an infinite mode set, and monotone retained probability under cutoff refinement.

M11.3 — QDO-calibrated LJ and ATM interactions

Verifies:

• E_LJ = ljRepulsive - ljAttractive;
• the m=6 tail is exactly -C6_LJ/r^6;
• C6_LJ = C6_QDO = 3/4 alpha1^2 hbar omega;
• alpha1 C6 = 4 C9, with C9 = 3/16 alpha1^3 hbar omega;
• far-field slope -6;
• ATM equilateral factor 11/8 and linear factor -2;
• ATM permutation symmetry and uniform R^-9 scaling.

M11.4 — optional QCD sector

Reuses the existing M10 implementations for matrix-valued periodic SU(3) links, local gauge transformations, covariant hopping, the exact matter propagator, and Gauss diagnostics. The neutral QDO sector remains independently executable.
