Let $f(x)=\ln x$, $g(x)=ax+1$, where $a\in \mathbb{R}$, and $F(x)=f(x)-g(x)$.  
$(Ⅰ)$ Find the equation of the tangent line to the curve $y=f(x)$ at $x=1$.  
$(Ⅱ)$ Determine the intervals where the function $F(x)$ is monotonic.  
$(Ⅲ)$ If the graph of the function $f(x)=\ln x$ always lies below the graph of $g(x)=ax+1$, find the range of real numbers for $a$.
