Walkthrough

This PR updates sysconfig configuration handling by replacing boolean literals with integer equivalents for Py_GIL_DISABLED and Py_DEBUG, adding runtime-dependent path variables (prefix, exec_prefix, BINDIR) to build-time configuration, and introducing ABIFLAGS constant. A .gitignore pattern is also added.

Poem

A rabbit hopped through configs with delight, 🐰
Swapping booleans for integers bright,
With paths and flags now set just right,
The sysconfig dances in Python's light! ✨
