cpu-parking-disabler

Shows how many cores Windows has parked right now and the four power
settings behind it, then sets Core Parking Min Cores (CPMINCORES /
CPMINCORES1) to 100 and Energy Performance Preference (PERFEPP / PERFEPP1)
to 0 on the active power scheme, for AC and DC, and shows the parked-core
count again so the effect is visible on screen.

Supports Intel 12th gen+ hybrid CPUs (separate P-core/E-core settings) and
non-hybrid CPUs (AMD Ryzen, older Intel), where the Class 1 (P-core)
settings do not exist and are skipped. Dual-CCD X3D Ryzens (7900X3D,
7950X3D, 9900X3D, 9950X3D) get a warning first: AMD parks the non-V-Cache
CCD during games THROUGH core parking, and this tweak defeats that.

The previous values are written to parking_undo_<stamp>.json next to the
script before anything changes; -Undo puts them back. The script relaunches
itself as Administrator when needed.
