Rust SDK 0.4.2

Released .

Rust SDK 0.4.2 follows 0.4.1 with patched zstd and Tokio dependencies that address RustSec security advisories. No API migration is needed from 0.4.1, and Rust 1.91.0 remains supported.

Upgrade

Update the SDK and the HTTP decompression dependency, then commit Cargo.toml and Cargo.lock:

cargo add scopedb-client@0.4.2
cargo update -p compression-codecs

Existing lockfiles should resolve compression-codecs to 0.4.46 or later so HTTP response decompression also uses patched zstd dependencies.

Applications upgrading from 0.3 should also follow the 0.3-to-0.4 migration steps.
