Test build 2: #102 resize on Hyprland

Second test build for #102: the meter jumping left when you press the resize corner on Hyprland, and back when you let go. Not a release: the meter won't offer it as an update.

Built from main at be1f1f6. The first test build still grew the window for the drag, and Hyprland keeps a floating window centred when an app resizes it. This one lets Hyprland run the resize itself, as KDE and GNOME do, so the left edge should stay put.

Install (Arch/CachyOS): sudo pacman -U a2tools-dps-meter-2.0.86.r891.gbe1f1f6-1-test102b-x86_64.pkg.tar.zst
Debian/Ubuntu: sudo apt install --reinstall ./a2tools-dps-meter_2.0.86-test102b_amd64.deb
Fedora: sudo dnf reinstall ./a2tools-dps-meter-2.0.86-test102b.x86_64.rpm (or dnf install if no 2.0.86 is installed)

The .deb and .rpm carry version 2.0.86 inside, the same as the release, so they need the reinstall commands above to replace an installed 2.0.86.
