Update Zed install to include Omazed (theme sync package) install and setup

[APS6]

This PR adds automatic installation of Omazed.

PS: This is my first time making a PR.

Omazed is a lightweight Bash + systemd package that:

• Automatically syncs Zed’s theme with your current Omarchy theme.
• Includes the 11 default Omarchy themes.
• Generates custom Zed themes from Alacritty configs on the fly (fast with bash).

As a Zed user myself I wanted to make the experience better for everyone and not just me. Since theme switching for all apps was previously considered out of scope in #719, I decided to make a separate, opt-in package. The goal was to keep it as lightweight and easy to set up as possible.

How it works

• A systemd service uses inotify-tools to watch the current Omarchy theme.
• On change, it runs a simple Bash script to update Zed’s theme.
• Resource usage is very low (about 5 MB of memory in my testing):

To make the install simple I added the package to AUR so that everything can be setup in seconds with yay -S omazed && omazed setup

Change in this PR

The Zed installer entry now also installs and sets up Omazed:
*Zed*) present_terminal "echo 'Installing Zed...'; sudo pacman -S --noconfirm zed && yay -S --noconfirm omazed && omazed setup && setsid gtk-launch dev.zed.Zed" ;;

That's it! Omazed handles everything else.

This way, users who choose Zed from the Omarchy installer get theme sync out of the box. Omarchy itself carries no extra burden since Omazed is fetched from the AUR.

Omazed is MIT-licensed and open source, so changes or improvements can be made freely.

Proposal

To make Omazed even lighter, I’d like to propose either:

• A file that always contains the current theme name (not a symlink), so I can drop the inotify-tools dependency and switch to systemd.path, or
• Even better, a way to hook into omarchy-theme-set directly, removing the need for file watching entirely.
