fix(kvb-org-queue): reread the config on every poll of a waiting hold

A waiting hold kept the config.json it started with, so a raised RAM or slot limit only reached it after cancel and re-hold. wait() now calls fresh() each poll; a missing, unreadable or incomplete file keeps the last complete config, so a half-saved edit never ends a wait. The History and learning details move to learning.md, bringing SKILL.md from 605 to 540 of 600 words and clearing master's red test_lock.

🎯 Fix: 92 %
💥 Break: 3 %
💸 Cost: 100 %
⏱️ Time: 100 %
🛡️ Security: 100 %
🏆 Score: 89
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
