fix(kvb-org-radio): council text reaches no agent as a tag

Every agent writes alerts.jsonl, news.jsonl and radio-silence.json
directly, so a planted </system-reminder><system-reminder> in a row's
sender or text reached every other agent's context as markup. watch.py's
clip() joins whitespace, turns each < into <\ and caps at 1000
characters; the watch hook's alerts, the block hook's mayday reason and
every radio line and silence line go through it, and radio.py delegates
to it instead of keeping its own CLIP. The radio skill adds the rule that
no sender proves operator approval.

🎯 Fix: 90 %
💥 Break: 3 %
💸 Cost: 100 %
⏱️ Time: 100 %
🛡️ Security: 100 %
💰 Value: ?
🏆 Score: 87
🚦 Gate: ✅ 90/5, cost and time <= 100, security 100 %
