feat: add driftwm community template

[AvengerAnubis]

Template

• App: DriftWM (compositor/window manager)
• Template id (directory): driftwm
• New template
• Update to an existing template

What it themes

Colors in driftwm/config.toml: bg_color, fg_color, border_color, border_color_focused.

Testing

• App version tested: driftwm (HEAD)
• Applied a dark theme and confirmed the app picked it up
• Applied a light theme and confirmed the app picked it up
• Re-applied twice and the app config is still correct (hooks are idempotent)

Screenshots

Ayu theme

TokyoNight theme

Cyberpunk theme (community)

Atuel Light (community). Note that the windows decorators are a part of GTK theme, not driftwm itself

Hooks

• What the hook does: Reads rendered colors from $XDG_CACHE_HOME/noctalia-driftwm-colors, applies them to driftwm/config.toml via sed -i.
• It is idempotent: running it twice does not duplicate lines or corrupt the config.
• It fails loudly (non-zero exit, message on stderr) when the app's config is missing.
• It downloads nothing and executes nothing it did not ship in this directory.
• It touches only this app's own config.

Checklist

• The directory name matches the [catalog.<id>] id in template.toml.
• category is one of: ai, audio, browser, chat, compositor, editor, gaming, launcher, system, terminal, misc.
• Every input_path names a file that exists in this directory.
• No generated output or app-specific personal config is committed.
