16/// Claim rent from compressible token accounts via the registry program
17///
18/// This function invokes the registry program's claim instruction,
19/// which then CPIs to the compressed token program with the correct compression_authority PDA signer.
20///
21/// # Arguments
22/// * `rpc` - RPC client with indexer capabilities
23/// * `token_accounts` - List of compressible token accounts to claim rent from
24/// * `authority` - Authority that can execute the claim
25/// * `payer` - Transaction fee payer
26///
27/// # Returns
28/// `Result<Signature, RpcError>` - Transaction signature
