feat(skills)!: rename the skills category to skill

kvb-skills-dream, -tune, -auto, -essence and -transcend become kvb-skill-*, and tests/test_naming.py now requires the category skill. enable-plugins.js registers the reminder hooks under the new names and repoints hook commands of the previous kvb-skills-* paths as well as the older autotune/dream paths; test_dream covers both generations. References in kvb-check-confidence, kvb-org-perform, kvb-org-rasci, kvb-transcend, the tests and the README organigram and skill map follow. The header comments of both reminder hooks and enable-plugins.js are dropped.

BREAKING CHANGE: /kvb-skills-dream, /kvb-skills-tune, /kvb-skills-auto, /kvb-skills-essence and /kvb-skills-transcend are now /kvb-skill-*.
