A virologist researching antiviral therapies models viral load dynamics with the function \( V(t) = V_0 \cos^2(\omega t + \phi) \), where \( V_0 \) is the maximum viral load, \( \omega \) is the angular frequency, and \( \phi \) is the phase shift. If \( V(0) = \frac{V_0}{2} \) and \( V\left(\frac{\pi}{2\omega}\right) = 0 \), find \( \phi \).
