torchbutton v1.1.5

Icon refinement — the power-ring gap now has two flat, vertical, symmetric ends
(the gap is a vertical slot rather than the lightning-bolt outline, which
previously slanted the right end). Slightly thinner ring. No functional changes
from v1.1.4.

Install

```sh
adb push torchbutton-v1.1.5.zip /data/local/tmp/torchbutton.zip
adb shell su -c 'magisk --install-module /data/local/tmp/torchbutton.zip'
adb reboot
```
Or Magisk app → Modules → Install from storage.
