Konstantin Shcheglov e730a62688 DeCo. Centralize resolver scope helpers in ScopeContext.
Expand ScopeContext into the single place that manages resolver
name-scope transitions, and migrate visitors to use it directly.

ScopeContext now:
- Owns the current name scope and handles push/pop via withScope().
- Provides focused helpers for common resolver scopes:
  - withLocalScope(), withInstanceScope(), withExtensionScope()
  - withTypeParameterScope() and withTypeParameterList()
  - withFormalParameterScope()
  - withConstructorInitializerScope() and withPrimaryParameterScope()
  - withDocImportScope() for documentation comment resolution
- Renames walkMixinDeclarationScopes() to visitMixinDeclaration() and routes
  mixin traversal through the shared helper.

Update ResolutionVisitor, ScopeResolverVisitor, and ReferenceResolver
to:
- Remove temporary routing getters/methods and ad-hoc try/finally scope
  management.
- Use the new ScopeContext helpers for consistent scoping across declarations,
  function bodies, and DeCo/primary-constructor-related initializer contexts.
- Reduce duplicated scope wiring and keep scope behavior localized for easier
  future evolution.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

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).
