Bernardo Magri d2b508485a fix(theme): hot-reload btop and opencode on theme switch
Phase B verdict on two unused? scripts — both inline comments
claimed they were "used by the Nomarchy theme switching", but the
switcher (themes/engine/scripts/nomarchy-theme-set) only restarted
walker, waybar, and the wallpaper service. So btop and opencode
stayed on the old palette after `nomarchy-theme-set <foo>` until
the user closed and reopened them by hand.

Wires both into nomarchy-theme-set, alongside the existing walker /
waybar restart calls. The check-then-call (`command -v ... &&`)
matches the surrounding style — a missing helper is a no-op, not a
fatal.

SCRIPTS.md regenerated: unused? 36 → 34, kept 163 → 165.
