CLAUDE: bundle L1+L2 TorchScript models as resources (piece 4A)

Bundles the exported TorchScript models + their .meta.json sidecars under
src/main/resources/cuas_dnn/<name>/ so CuasDnnLocal runs with no local model
dir (deployment needs no PyTorch/dev tooling - just the .so + libtorch runtime):
  weighted9_pm_s/model.ts.pt (+.meta.json)        L1 (N=9,P=24,vr=5,out_ch=124)
  mexhat_gaps_boost40/model.l2.ts.pt (+.meta.json) L2 (ch_hidden=24,vmax=1.4)

Validated: CuasDnnLocal bundled-resource path (curt_dnn_local_dir empty) extracts
from the jar and matches the server oracle EXACTLY (offset5=0.0, roi=0.0).
