Respalda el grueso de la configuración de usuario aún no versionada

Añade config KDE/Plasma (atajos, energía, splash, kwin rules, spectacle,
xdg-portal, mimeapps...), systemd user (incluye el delay de arranque de
Davmail), autostart, apps varias (GIMP, vlc, kate, btop, go, okular...),
temas Vampire-Light/Vampire-dark completos con su splash embebido, y
credential.helper en el template de gitconfig.

Excluye explícitamente en .chezmoiignore lo que NO debe ir a un repo git:
tokens OAuth de Davmail, secreto maestro de Remmina, clave privada de
KDE Connect, logs de KVIrc, IP pública en prefs de Spotify, perfiles de
navegador, vaults (Bitwarden/KWallet/keyrings), caches binarias y
credenciales en texto plano.
