SPT-3G D1 T&E likelihood runtime data for SPTLikelihoods.jl

Runtime data artifact for the native Julia implementation of the full SPT-3G D1 T&E likelihood in SPTLikelihoods.jl. The archive contains the converted bandpowers, covariance, window functions, foreground templates, beam data, and provenance ledger required by the SPT3G_D1_TnE_v0 likelihood. It is derived from the pinned spt_candl_data release revision bfe809a140087d19412aa6bc8c8d4ba18840b315; metadata.json inside the artifact records source file hashes and conversion details.
