eole with position_encoding_type: Relative scores the relative-key term with an unscaled query ((Q Kᵀ) / sqrt(d) + Q R_kᵀ). CTranslate2 applies queries_scale = 1/sqrt(d) to both terms. The eole converter copied the same embedding table into relative_position_keys and relative_position_values, so the key term was sqrt(d) times too small.

This pre-scales relative_position_keys by sqrt(dim_per_head) and leaves relative_position_values unchanged.
Fixes #2134
