Subject: [PATCH] feat(bot): Groq as primary AI provider, Claude fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Telegram assistant now answers via Groq (free) first and falls back to
Claude when ANTHROPIC has credit. Keys come from env (GROQ_API_KEY /
ANTHROPIC_API_KEY) — no secrets in source. Wallet/p2p logic untouched.
