docs(llms-cli): align prototype tier wording with v1.41.0

Reflect GH-110 fix in the agent-facing CLI reference: the prototype
tier is \$0.10/7d but free via the built-in testnet faucet. Matches
what `run402 tier --help` and the MCP tool descriptions now say.

 ## TL;DR
 
-Run402 gives you a full Postgres database with REST API, user auth, file storage, row-level security, static site hosting, serverless functions, and image generation. **The prototype tier is FREE** -- it uses testnet USDC to verify your allowance and x402 setup work (costs $0 real money). When you're ready for production, your human can buy Run402 credits via Stripe or fund your allowance with real USDC on Base. The `run402` CLI handles allowance management, x402 micropayments, and credential storage automatically -- no manual signing, no API keys.
