CRE TS SDK v1.6.0 — Custom Rust Plugin Support and Non-Determinism Warnings

TypeScript SDK version 1.6.0 is now available. This release adds custom Rust plugin support — you can now inject Rust logic into your TypeScript workflows using the new --plugin flag in cre-compile, providing a pre-built .plugin.wasm compiled from your own Rust crate. The SDK ships example packages (@chainlink/cre-rust-inject-alpha, @chainlink/cre-rust-inject-beta) and a prebuilt plugin example to help you get started. This release also adds compile-time non-determinism static analysis: the SDK now emits warnings during cre workflow build and cre workflow simulate when it detects potentially non-deterministic patterns such as Date.now(), Math.random(), or Promise.race().
