VVLTC parameters tweak Some notes: - Both tests were conducted on top of #5848. - Based on tuning suggestions, the extension for capturing the previously moved piece was removed/simplified. (Developers can attempt to reintroduce it post-merge if needed.) - Initially, bonusScale = std::max(bonusScale, -2); was included but later removed in the second test upon Viz's request, however, it was nearly non-functional anyway.
