[Bug]: useAccount returns incomplete account data (missing owner, executable, data)

[resourcefulmind]

Steps to Reproduce

import { useAccount } from "@solana/react-hooks";

// Fetch Token Program account
const account = useAccount("TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA");

console.log(account);
// Result:
// {
// lamports: 8468205194,
// owner: null, // ❌ Should be BPFLoaderUpgradeab1e...
// executable: null, // ❌ Should be true
// data: null // ❌ Should contain program bytecode
// }## Expected Behavior

For the Token Program, useAccount should return:

• lamports: 8468205194 ✅
• owner: BPFLoaderUpgradeab1e11111111111111111111111
• executable: true
• data: program bytecode (or at least data length)

Actual behavior

Actual Behavior

Only lamports is populated. All other fields are null.

Test Results

Account	lamports	owner	executable	data

Token Program	8468205194	null	null	null

PR #126 adds owner and executable fields to AccountCacheEntry.

Regarding rentEpoch: While this field exists in the raw Solana RPC response, it's not included in the @solana/kit typed response. This is likely because all Solana accounts are now rent-exempt (mandatory since 2022), making the field effectively deprecated - it always returns u64::MAX for rent-exempt accounts.

If rentEpoch is needed, it would require either a PR to @solana/kit to add the field to their types, or using type assertions to access the raw response.
