Writing a minimal implementation of a dynamic array in C, inspired by C++ STL's std::vector.

This project is part of my effort to get more comfortable with low-level programming in C. I really enjoy working with C (and C++) for the level of control they provide over memory and performance. Before making more complex stuff like a custom memory allocator (s-memalloc, which is ongoing actually, but I felt the need to warm up a bit before continuing), I’m starting with smaller components to strengthen my understanding of memory management and data structures. While I’ve implemented data structures in C while learning data structures and algorithms for the first time and for further practice, I haven’t built standalone C projects before. This is the first step I’m taking to change that.

Integer-only for now, for the sake of simplicity.

All the functions use the sv_ prefix (e.g., sv_init, sv_push_back, sv_pop_back, sv_free).
sv stands for s-vector.

Why a prefix?
Since C has no namespaces, a generic name like push_back (like C++'s std::vector) could collide with other libraries or my future programs.

So, the prefix:

• Avoids any conflicts.
• Makes the functions' duty obvious (as they work on my s_vector).
