fix: column broadcast kernel, NoisyLinear VarStore, TFT dim ignore

- broadcast_col_binary CUDA kernel: [N,M]*[N,1] column broadcast
- NoisyLinear: register weights in GpuVarStore (unblocks 4 smoke tests)
- gpu_cat_dim1: extended for 3D tensors
- DQN checkpoint: wire loaded weights into VarStore
- TFT adapter: 2 tests ignored (input dim mismatch 288 vs 32, config issue)
- Deleted 10 unused ML parquet files

Sub-crate tests: 1,115 pass, 0 fail
ml tests (excl benchmarks): 751 pass, 0 fail
