Subject: [PATCH] fix(mina-consensus.ts): correct the splice index in
 filterBestTip (#93)

The previous implementation was incorrectly splicing from the start of
the array, which could lead to unexpected results. The fix ensures that
the splice operation starts from the correct index, preserving the
integrity of the array.
