"""Create commitments for all positions at once (vectorized).

Produces bit-identical results to calling create_commitment() in a loop.

Args:
h_layer: Hidden states [seq_len, hidden_dim] on any device.
r_vec: Coefficient vector [topk] (int8, typically on CPU).
projected_s_vals: Optional pre-computed s_vals (for deterministic mode).
Currently not used; exists for compatibility with the miner's
fixed-point projection path.

Returns:
List of commitment dicts, one per position.
