`cargo test -p iceberg-sqllogictest` fails to compile: missing tokio `rt-multi-thread` feature

Describe the bug

Running cargo test -p iceberg-sqllogictest in isolation fails to compile with:

error[E0599]: no function or associated item named `new_multi_thread`
found for struct `tokio::runtime::Builder`
--> crates/sqllogictest/tests/sqllogictests.rs:28:39

tests/sqllogictests.rs calls tokio::runtime::Builder::new_multi_thread(), which requires the tokio rt-multi-thread feature. But crates/sqllogictest/Cargo.toml declares tokio = { workspace = true }, and the workspace root sets default-features = false with no features - so rt-multi-thread is never enabled for this crate.

To Reproduce

git clone https://github.com/apache/iceberg-rust
cd iceberg-rust
cargo test -p iceberg-sqllogictest

Expected behavior

The crate should compile and tests should run successfully when built in isolation.

Note: the bug is invisible with make build (--all-features --workspace) because crates/examples enables tokio = { features = ["full"] }, and Cargo features are additive across the workspace graph.

Willingness to contribute

I can contribute a fix for this bug independently
