Add support for ghostty theme switching

[rossvz]

Even though Alacritty is the default Omarchy theme, it may be helpful to support other terminals.

This adds a ghostty-config file to each theme preset that matches which theme ghostty should use.
Most of these config themes are 1-1 with the presets, with the exception of Matte Black which uses a custom palette definition.

User would need to set up their local ghostty config to do something like

config-file = ?../omarchy/current/theme/ghostty-theme`

to conditionally apply the config from omarchy.

reloading config

at this time ghostty doesnt support programmatic reloading - so we use hyprland to iterate through any open windows and send the keyboard shortcut for reloading (CTRL SHIFT ,)

update Using the Ghostty tip, we can use pkill -SIGUSR2 ghostty to reload config

Ghostty tip (will be 1.2) supports programmatic config reloading via SIGUSR2 and systemd integrations and we’ll probably also add a dbus API before release. The signal works now for tip builds.

Happy to take this as we prepare for Ghostty being the terminal, but yes, let's target the SIGUSR2 way of triggering the config reload right away.

We could also consider having a omarchy-setup-terminal script that allows you to toggle between Alacritty and Ghostty for the moment. It's just that we need to use the ghostty-git dependency, which clocks in at about 1GB and a million dependencies, so should probably do something like "Ghostty (beta)" for the selector.

We also need to add the ghostty config to all the extra themes: https://manuals.omamix.org/2/the-omarchy-manual/90/extra-themes

@dhh - this is updated to use SIGUSR2 for reload. Do we want to wait for Ghostty to support this on main before merging?

re: the other themes, I can create issues in the separate theme repos indicating the expected ghostty-theme file that should be added, but we may want this landed on master first?

When do you think this is going to be a thing?

@dhh with Ghostty out this could be close - I noticed that a lot of theme names have changed with 1.2 release so I can work on updating the relevant files.

Should this be part of the #1568 effort?

[dhh]

I tested all the theme names with Ghostty 1.2. So think they're correct on dev.

Got it - I think this PR isn't needed then, I didn't realize we had pulled all the theme work in that 3.0 update already
