omarchy-nvim-setup hardcoded theme.lua to the Omarchy 4 theme location (~/.local/state/omarchy/current), which doesn't exist on Omarchy 3.x, so fresh 3.8.3 installs errored on nvim startup with "Failed to load plugins.theme" (basecamp/omarchy#6309). Detect the right location at runtime: prefer whichever current-theme directory exists, and fall back to the installed Omarchy version for fresh 3.x installs where setup runs before the first theme is set.
