Description: The LP token calculation uses the geometric mean (square root of product) which can lead to rounding errors and potential value extraction. The current implementation doesn't account for these rounding errors properly.

Impact: Users might receive slightly fewer LP tokens than they should, or the pool might accumulate dust amounts that can't be withdrawn.

Recommended Mitigation: Implement a more precise LP token calculation method that accounts for rounding errors, or add a small buffer to ensure users receive at least the calculated amount.
