The integer sequence \( \left\{a_{n}\right\} \) is defined as follows:
$$
a_{0}=3, a_{1}=4, a_{n+2}=a_{n+1} a_{n}+\left\lceil\sqrt{\left(a_{n+1}^{2}-1\right)\left(a_{n}^{2}-1\right)} \right\rceil \text{ for } n \geq 0.
$$

Find the value of \( \sum_{n=0}^{+\infty}\left(\frac{a_{n+3}}{a_{n+2}}-\frac{a_{n+2}}{a_{n}}+\frac{a_{n+1}}{a_{n+3}}-\frac{a_{n}}{a_{n+1}}\right) \).
