Install tensaku on Omarchy

Tensaku is a screenshot annotation app for Wayland desktops (Sway, Hyprland, and other wlroots-based compositors), forked from Satty. You take or paste a screenshot and add arrows, boxes, freehand marks, text callouts, and blur/redaction, with the twist that every annotation stays a movable, resizable object organized in a layers panel rather than being burned in immediately. It also supports stitching scrolling screenshots of tall content into one image.

Open a terminal.
Run the install command:
```
omarchy pkg add tensaku
```
Check it landed. Pacman should list version 0.29.0-2:
```
pacman -Qi tensaku
