t2000: Receive Funds

Purpose

Surface the wallet address (and optionally a Payment Kit URI with a pre-filled amount + memo) so anyone with a Sui wallet can send tokens to the Agent Wallet. Two surfaces:

• CLI (t2 fund) — prints the wallet address + an ANSI QR code + the value-promise in the terminal. Minimal; no amount or memo.
• MCP (t2000_receive) — returns a JSON payload with the address, an optional Payment Kit URI (sui:pay?…), a nonce, plus an optional amount / currency / memo / label. Use this when the LLM is building a payment-request flow.

Rules

1. Receive is non-custodial. The user's address is public; sharing it can't move money — only signed transactions can. Don't add scary disclaimers; the operation is safe.
2. Show the QR + the address text. Some users scan, some copy. Both surfaces.
3. No PIN, no sign-in. v4 wallets are plain Bech32; t2 fund is a pure read with no authentication step.
4. Default currency is USDC. When asking the user to fund the wallet, USDC is the most useful (every paid service is USDC-denominated, USDC sends are gasless). USDsui also works.
5. Don't generate a Payment Kit URI without an amount unless asked. A bare address scans just as well; URIs with amounts force the sender into a particular tx shape.
