Refactored AcBinarySourceGenerator to use RefAwareEmitPredicate for all ref-handling switch decisions, ensuring child property ref-marker logic is based solely on child compile-time flags. Fixed deserialization drift when parent disables ref-handling but child enables it. Added regression tests and new test models to verify correct round-trip behavior for duplicate child references in collections and dictionaries. Improved XML docs and updated conventions for summary tags. Added SGen string round-trip tests for medium UTF-8/ASCII cases.
Split AcBinarySourceGenerator.cs into multiple partial class files for improved maintainability and clarity. Each major concern (models, type analysis, class info extraction, writer/reader emit, diagnostics, and module init) now resides in its own file. Updated .gitignore and settings.local.json to support the new structure. No functional changes to generator output; this is a pure organizational refactor.
