7d45d00d6a docs(generator): improve and unify English documentation and examples for all DI source files
- Added comprehensive English documentation for all DI generator and support files:
  * inject_generator.dart — full class/method doc-comments, usage samples
  * module_generator.dart — doc-comments, feature explanation, complete example
  * src/annotation_validator.dart — class and detailed static method descriptions
  * src/type_parser.dart — doc, example for ParsedType and TypeParser, specific codegen notes
  * src/bind_spec.dart — interface, static factory, and codegen docs with DI scenarios
  * src/bind_parameters_spec.dart — details and samples for code generation logic
  * src/metadata_utils.dart — full doc and examples for annotation utilities
  * src/exceptions.dart — user- and contributor-friendly errors, structured output, category explanations
  * src/generated_class.dart — usage-centric doc-comments, example of resulting generated DI class
- Removed Russian/duplicate comments for full clarity and maintainability
- Ensured that new and existing contributors can easily extend and maintain DI code generation logic

BREAKING CHANGE: All documentation now English-only; comments include usage examples for each principal structure or routine

See #docs, #generator, #cherrypick

  * Binding<T>
  * BindingResolver<T>
  * CycleDetector and CycleDetectionMixin
  * GlobalCycleDetector and GlobalCycleDetectionMixin
  * Factory<T>
  * Module
  * Scope
- Each public and private method is now documented in clear DartDoc style with usages
- Added code samples for modules, scope, subscopes, DI resolve/async, cycle detection
- Russian comments completely replaced with English for consistency
- NO logic or API changes, documentation and devex improvement only
