Angular Previews ngp, a Rust-Based Compiler Preprocessor for TypeScript 7

The Angular team has released ngp, a compiler preprocessor that rewrites the analysis stage in Rust using Oxc. It replaces ngc's dependence on the TypeScript Transformer API, which TypeScript 7.0 removed, and an early benchmark showed 2x to 3x faster cold builds. Adoption is expected in a future Angular 22 minor release, and production builds should stay on ngc until then.

Why it matters: Teams upgrading to TypeScript 7 need to know that Angular's build pipeline depends on this change and that ngc remains the production path for now.
