This pull request refactors the Angular compilation pipeline by centralizing TypeScript compiler options transformation into a new transformCompilerOptions utility and replacing the callback-based transformer with a structured CompilerOptionOverrides object. This change simplifies the parallel worker communication by eliminating the synchronous Atomics-based message channel. Feedback on the changes highlights an issue where transformCompilerOptions mutates its input parameter directly instead of cloning it, and points out inconsistencies in how NoopCompilation manually overrides compiler options compared to the main transformation logic.
…d remove worker options IPC Move the TypeScript compiler options transformation logic from compiler-plugin.ts into transformCompilerOptions in the compilation layer. This replaces numeric literal values with strongly-typed TypeScript enums and encapsulates options normalization within the compilation classes. Replace the optionsChannel, optionsSignal, and synchronous Atomics barrier between the main thread and the compilation worker thread with serializable CompilerOptionOverrides passed during initialization. Any compiler options transformation warnings are now returned directly in AngularCompilationResult.warnings rather than mutating a main-thread array.
