Import InvokeHostFunctionResult.
decode_test.rs uses InvokeHostFunctionResult without declaring or importing it. The test target cannot compile until the type is added to the stellar_xdr::curr import list.

Register decode_test as an explicit Cargo test target. crates/cli/Cargo.toml has no [[test]] entry, and Cargo does not auto-discover tests nested below crates/cli/tests. Add a target with path = "tests/integration/decode_test.rs".

$## Description
Add an end-to-end integration test for the decode command loop that validates CLI argument routing, decode routines, and report printing against a simulated transaction context.
