Fine. Persist type erasure and self-ref flags for extension types Capture more observable facts about extension types in fine-grained manifests to improve matching and invalidation. This change persists additional fields on `ExtensionTypeItem` and uses them during matching: - `typeErasure` - `representationType` - `hasImplementsSelfReference` - `hasRepresentationSelfReference` It updates encode/decode/write paths, extends `match()` to compare the new fields, and teaches the result printer to display the flags and types when element manifests are enabled. The analyzer data format is bumped (`DATA_VERSION` 532 → 533) to invalidate stale caches. Motivation: - Make manifest identities reflect changes to an extension type’s underlying representation and erasure. - Enable manifest-driven, flag-level invalidation without re-deriving from other properties. - Improve determinism and clarity in diagnostics and reuse decisions. Notes: - Existing behavior is preserved; changes primarily affect identity, reuse, and printed diagnostics. - Cache rebuilds are expected due to the version bump.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
