Replace warp-reduced atomicAdd gradient accumulation in the curiosity forward model with a two-kernel deterministic pipeline: 1. curiosity_fwd_bwd_per_block: each block reduces its threads' gradient contributions via shared memory tree reduction, writes one partial gradient vector [CUR_TOTAL_PARAMS] per block. 2. curiosity_grad_reduce: one thread per parameter sums block partials in fixed order (block 0, 1, 2, ...). Fully deterministic. Deleted kernels: curiosity_forward_backward (atomicAdd path), curiosity_fused_zero_fwd_bwd_adam (grid-wide atomic barrier), curiosity_adam_step_fused (dead code), warp_sum_cur helper. Rust side: removed block_counter, adam_fused_func, fused_zero_fwd_bwd_adam_func. Added partial_grads buffer [max_blocks * CUR_TOTAL_PARAMS] (~2.8 MB for 64 blocks).
