Adding Math Support

I’ve added support for mathematical formulas using LaTeX syntax (powered by remark-math and rehype-katex).

This allows to write inline math like $E=mc^2$ or block math for more complex equations.

How to use it

Wrap your formula in single dollar signs $:

The mass-energy equivalence is $E=mc^2$

Result: The mass-energy equivalence is $E=mc^2$

Wrap your formula in double dollar signs $$:

$$
f(x) = \int_{-\infty}^\infty
    \hat f(\xi)\,e^{2 \pi i \xi x}
    \,d\xi
$$

Result:

f(x) = \int_{-\infty}^\infty \hat f(\xi)\,e^{2 \pi i \xi x} \,d\xi

This will be super useful for future posts about algorithms, complexity analysis (Big O notation), and performance metrics!
