[2.2.5] Bug Fixes

Full Changelog: 2.2.4...2.2.5

• Fixed compiler warnings across the codebase (ignored return values from system(), fgets(), read()).
• fgets() calls now handle EOF properly instead of leaving buffers uninitialized — defaults to 'n' for all prompts, safe default.
• read() in version comparison now properly null-terminates the buffer instead of relying on zero-init.
• Cleaned up main() signature — was using non-standard unsigned int argc, switched to standard int argc.
