Claim: Connect-first wallet UX (Connect Wallet then SIWE)

[GsCommand]

Motivation

• Improve the Claim page authentication UX so the initial button never appears to do nothing by switching from a SIWE-first flow to an explicit connect-first flow.

Description

• Updated public/claim.html step 1 title and copy to Connect wallet and clarified that the wallet signs the login message while the Ed25519 key signs agent receipts.
• Replaced the single SIWE button with a primary Connect Wallet button and a secondary Sign-In with Ethereum button that is revealed after a successful connection, and added copy listing supported injected browser wallets (MetaMask, Rabby, Coinbase Wallet, and other EIP-1193 wallets).
• Implemented window.connectWallet to request accounts via ethereum.request({ method: 'eth_requestAccounts' }), surface clear errors (missing wallet, connection rejected), and display Wallet connected: 0x1234...abcd on success.
• Adjusted window.signInWithEthereum to run after connection, fetching /api/auth/nonce, building the SIWE message, requesting personal_sign, posting to /api/auth/verify, and mapping visible failure states including signature rejected, nonce request failed, SIWE verification failed, domain mismatch, and unsupported chain.
• Kept changes strictly frontend-scoped and avoided adding WalletConnect/AppKit, payment/provisioning features, ENS/ERC-8004 fakes, or backend endpoint modifications.

Testing

• Ran npm test in the repository and all automated tests passed (30 tests, 0 failures).
• Attempted npm install in the root which began but produced environment warnings; npm install for examples/webhook-auto-verify completed successfully.
• npm run build failed because the repository has no build script (expected failure).
• Ran examples/webhook-auto-verify checks via npm run check which succeeded.
