+Add companion wallet (beta) CWP provider with local key generation, AES-256-GCM encryption, signing (message, typed data, transaction), transaction broadcast via viem, session management with policy enforcement, fund command (transfer ETH from external wallet via WalletConnect), and drain command (sweep native tokens to destination)

+Migrate staking-cli from WalletConnect SDK to CLI Wallet Protocol (CWP).
+
+**cli-sdk**: Add send-transaction command, --chain flag for connect, --json flag for whoami, wallet-walletconnect CWP adapter binary, move log output to stderr for protocol cleanliness, and absorb CWP discovery/exec/select modules (previously @anthropic-ai/wallet-cli) under src/cwp/.
+
+**staking-cli** (BREAKING): Replace WalletConnectCLI dependency with CWP-based wallet discovery via @walletconnect/cli-sdk. Commands stake/unstake/claim now accept WalletSender interface instead of WalletConnectCLI. Remove --browser flag, add --wallet flag. status/balance now require --address flag. Remove CLI_METADATA export.
