Solana Wallet Standard adapter

With @pollar/react, pass the same adapter array to walletAdapters on <PollarProvider>; the built-in login modal renders a “Solana Wallet” gateway with one button per wallet.

Notes

Wallets register in the browser only: the factory returns [] during SSR, so build the client on the client render.
Login is SIWS, not SEP-10: the adapter declares chain: 'SOLANA', and a wallet without solana:signIn signs the same message through signMessage.
No network option: the Solana network follows the API key, like the Stellar one.
Narrow the list with wallets, rename buttons with labels, and change the gateway label with groupLabel (default 'Solana Wallet').
