[bug]: CoinbaseConnector no longer works with Base app (formerly Coinbase Wallet)

[dev-jaehan]

Description

The CoinbaseConnector from @reown/appkit-coinbase-react-native no longer works with the Base app (formerly Coinbase Wallet).

Since July 2025, Coinbase Wallet has been rebranded to "Base app" and existing Coinbase Wallet users were automatically migrated. The current CoinbaseConnector uses the legacy @coinbase/wallet-mobile-sdk, which is incompatible with the new Base app.

Symptoms:

• Base app opens successfully via deep link
• No approval screen appears in Base app - it just opens to the home screen
• When returning to the original app, no callback is received
• Connection never completes

Root cause:
The legacy @coinbase/wallet-mobile-sdk is designed for the old Coinbase Wallet app. The new Base app requires:

• Base Account SDK (@base-org/account), or
• Mobile Wallet Protocol (@mobile-wallet-protocol/client)
