PR #146 rewired the skills import to read from colibri instead of
clawdie-ai, but left the old import-clawdie-skills.sh in scripts/.
It is referenced nowhere (build.sh calls import-colibri-skills.sh)
and was never deleted. Remove it and fix the one stale comment in
import-colibri-skills.sh that still named the deleted script.
