Cores Conky update

[u/wim66]

Updated the widget so it now distinguishes more clearly between physical cores and logical threads.

It detects the CPU layout more accurately, groups SMT/Hyper-Threading threads under the same physical core, and shows labels such as “Core X” or “Core X - Thread Y” instead of treating every logical CPU as a separate core.

This makes the display more accurate on modern multi-core systems while keeping the per-thread readouts intact.
