Add Omarchy integration: theme catalog hot-reload + OSC52 clipboard

Intrepid now installs Omarchy's full colorscheme catalog and hot-reloads
by reading the theme spec omarchy-theme-set writes to
~/.local/state/omarchy/current/theme/neovim.lua, watched via vim.uv
(no lazy.nvim here, so this replicates its file-watch + reload behavior
directly). Other hosts are unaffected.

Also ports Omarchy's OSC52 remote-clipboard module so yanks still reach
the local Wayland clipboard/tmux/SSH client, matching the default
Omarchy nvim config's behavior in those sessions.
