feat: smart airdrop with faucet link, markdown chat, onboarding flow

- Replace unreliable devnet RPC airdrop with direct faucet.solana.com link
  containing user's wallet address pre-filled
- Add react-markdown rendering for assistant messages (bold, links, code, lists)
- Add first-time onboarding: welcome message with wallet address and faucet link
- Stop Prometheus metrics spam by stopping the container (services lack /metrics)
- Update system prompt with airdrop instructions for faucet link presentation

+### Airdrops
+When a user asks for test SOL or an airdrop, use the request_airdrop tool. It will give you a faucet link. Present it to the user as a clickable markdown link and show their wallet address. Example:
+"Here's your wallet address: \`abc123...\`
+
+Click here to get free test SOL: [Get SOL from Faucet](https://faucet.solana.com/?address=abc123&network=devnet)
+
+The faucet will send free devnet SOL to your wallet. Just click the link and confirm!"
+
 ### Formatting
 - Use backticks for addresses and transaction IDs
 - Use **bold** for amounts
