v2.0.0 — V7 protocol (testnet demo)

Z0tz Wallet v2.0.0 — V7 protocol (testnet demo)

Major release: the wallet is now fully V7-compliant, matching the desktop
GUI feature-for-feature.

Testnet only — arb-sepolia + base-sepolia + eth-sepolia. Do not store real funds.

What's new in V7

• One passkey → one smart account on every chain (CreateX, same address
  cross-chain). No seed phrase.
• Onboarding airdrop — create a wallet and claim 30,000 zUSDC across the
  three testnets in one tap.
• Confidential balances — your zUSDC is FHE ciphertext on-chain; balances
  reveal off-chain via a gasless viewer permit (@cofhe/sdk + TFHE in-app).
• Cash-in — sweep a stealth into the (account, token) confidential ledger.
• Send — to a z0tz name, to an account, or cash out to an EOA.
• Bridge (cross-chain) — zUSDC via the in-house CCTP clone, or canonical
  USDC via real Circle CCTP V2, with live progress.
• Names — register + resolve your z0tz name.
• Tezcatli yield — deposit/withdraw against the multi-asset yield vault.
• History — reconstructed from the z0tz DB, keyed by your passkey account.
• Backup & recovery — PIN-encrypted QR / ZIP vault, byte-compatible with the
  desktop app; restore on a fresh install from the welcome screen.
• Settings — native zUSDC always on; enable canonical USDC support.
