Increase cap text limits to match skill lexicon
text: 3000/300 → 50000/15000, description: 3000/300 → 10000/1024.
Backwards-compatible constraint relaxation — matches org.v-it.skill limits.
Original limits were inherited from app.bsky.feed.post, not an intentional
product choice. Structured caps need room for intent, scope, risk assessment,
and implementation guidance.
