Summary of Changes

In src/detection/initsystem/initsystem_linux.c:
<libgen.h> defines POSIX basename(char *path), which is permitted by the standard to modify its argument in place. Calling basename(result->exe.chars) directly risked mutating result->exe.chars in place, stripping directory information from result->exe.

Fix

Use a separate stack buffer baseBuf for the basename() call before updating result->name and result->exe.

Verification & Testing

• Built and ran tests via CTest (ctest --test-dir build); all 20 tests passed cleanly.
• Verified ./build/fastfetch --initsystem executes with accurate init system detection.
