loka_light: Compact multipolar toolkit for n-polar information systems

1.4.1 — 2026-03-13 Hardened antenna and receiver compatibility checks: pole-count validation, loka/polarity metadata matching, and keyed frequency gating now live directly in the device pipeline. Integrated SigmaGuard into receiver-side purification flows and aligned secure_transmission / property_transfer_chain with the explicit O2 cleanup path. Expanded theory-facing coverage for odd-N cascades, translation-gap branches, probability_tensor(), and clean-state witness/noise validation. Reworded tetradic/pseudo-quantum helper metadata so complex arithmetic, phase operators, and direct composition are clearly marked as projection/reference vocabulary rather than primary multipolar law.
