fix(home): resurrect process list + track zed settings in dotfiles 🏠

tmux-resurrect only restores programs in its allow-list; nvim/claude/ssh
were missing so restored panes came back as bare fish prompts. Adds the
three programs with argv-aware restart patterns.

Also wires ~/.config/zed/settings.json as an xdg.configFile symlink so
Zed config survives machine rebuilds alongside the rest of dotfiles.
