Given that $\left\{a_{n}\right\}$ is an arithmetic sequence, and $\left\{b_{n}\right\}$ is a geometric sequence, with $b_{1}=a_{1}^{2}$, $b_{2}=a_{2}^{2}$, $b_{3}=a_{3}^{2}$ (where $a_{1}<a_{2}$). Additionally, $\lim \left(b_{1}+b_{2}+\cdots+b_{n}\right)=\sqrt{2}+1$. Determine the first term and the common difference of the sequence $\left\{a_{n}\right\}$.
