fix(cli-sdk): add multi-chain gas support, refuel, and receipt verification

[arein]

Summary

• Expand EVM chain support from 3 to 8 chains with per-chain gasToken and gasCost rankings
• Add automatic gas refuel before cross-chain bridges — detects when destination chain has no native gas and bridges a small amount first
• Add on-chain receipt verification after send-transaction — reports confirmed/reverted with gas usage
• Export rpcUrl, waitForReceipt, and TxReceipt for downstream CLI consumers (e.g. hyperliquid-cli fund command)
• Smart source chain selection: prefer cheapest gas chains with sufficient balance
• Use per-chain gas token names (POL, HYPE, etc.) instead of hardcoded "ETH"
• Add Hyperliquid (HyperEVM, eip155:999) to default EVM chain aliases

Test plan

• pnpm build passes across all 5 packages
• walletconnect swidge tested end-to-end (ETH→USDC cross-chain)
• walletconnect send-transaction receipt verification tested (confirmed + reverted cases)
• Refuel logic tested (auto-bridge gas to destination chain)
• TTY prompt path for refuel (interactive y/n)
• Non-TTY pipe mode auto-refuel
