Remove the MAX_ANCHOR_WIDTH=100 constant and the corresponding clamp on anchorWidth in LiquidityManager.recenter(). The optimizer is now free to choose any anchor width; evolution run 7 immediately exploited AW=153. Update IOptimizer.sol NatSpec to reflect no clamping. Update the testAnchorWidthAbove100IsClamped test to testAnchorWidthAbove100IsNotClamped, asserting the tick range matches the full AW=150 width.
