Key Changes

Allocator Refactoring

• Replaced direct allocator usage with Code.scope((allocate) => ...) pattern
• Allocation now deferred until final code emission stage via DartEmitter
• Improves separation of concerns and makes code more testable

Formatting Support

• Added dartFormatter() configuration function
• Support for custom page_width and language_version in build.yaml
• All builders now receive configured DartFormatter instance
• Example configuration:

format:
  page_width: 80
  language_version: '3.7.0'

Version Updates

• gql_build: 0.12.0 → 0.13.0 (new features)

Test Plan

All existing tests pass. The generated code output remains functionally identical, with only formatting differences based on dart_style 3.0.0.
