Add omacharts (#802)

A fast, keyboard-driven charting app for Omarchy, built on GTK4 and
libadwaita. It follows the active Omarchy theme, generates an indicator
palette for whichever theme is in force, and ships a plugin for the bar.

Source build from the project's own tagged release, tracked by a GitHub
watch so version bumps come from the release feed. Not in the AUR.
