Refactor threading module: rename files & update refs 🌟

- Renamed `athr_thr.c` to `athr_thread.c`; `athr_thr.h` to `athr_thread.h`.
- Updated includes: `athr_thr.h` to `athr_thread.h` in `athr.c` and `athr.h`.
- Adjusted Makefile to exclude `athr_terminal_ioctl` files on Windows.
- Added `.PHONY` targets to Makefile for `all`, `check`, `uninstall`, and `clean`.

These changes clarify the threading module's purpose by using full word names
and enhance Makefile's organization and cross-platform consistency.
