feat(home): theme CLI tools, add staples, env defaults and mime apps

Browse Source 
- Catppuccin Mocha for fzf (colors), bat (catppuccin/bat tmTheme) and
  git delta (syntax-theme + navigate/line-numbers/side-by-side).
- CLI staples on every host: ripgrep, fd, jq, btop, plus gh (SSH) and
  tea (Gitea CLI).
- home.sessionVariables: PAGER, MANPAGER (bat), VISUAL; xdg.enable.
- xdg.mimeApps defaults (web->Firefox, directories->nemo).
- Document the stateVersion pin. README updated.
