A bug starts at a vertex of a grid made of equilateral triangles with a side length of $1$. At each step, the bug moves in one of the $6$ possible directions along the grid lines randomly and independently with equal probability. Find the probability that after $5$ moves, the bug will never have been more than $1$ unit away from the starting position. The original answer is in \(\frac{k}{m}\) format, please give the value of k + m.

Let's think step by step and output the final answer within \boxed{}.
