Expanded and clarified solution/project documentation:
- Added all top-level docs and docs/ folder as solution items in .sln files
- Inserted maintenance notices in all project and subfolder READMEs: require .md sync with code
- Main READMEs now include project tables with TFM, purpose, and README links
- ARCHITECTURE.md now details dependency graph and TFM rationale
- CONVENTIONS.md and copilot-instructions.md require code reuse, no redundancy
- Glossary and conventions updated to require terminology/rule updates with code changes
- Emphasized DLL-only AyCode.Core refs and nopCommerce .NET 9.0 requirement
- Clarified domain terms and intentional typos
- No code logic changes; documentation and guidance only
Replaced AcToonSerializer.Serialize with SerializeTypeMetadata<FullProcessModel> in ToonTests. The test now serializes only the type metadata for FullProcessModel using the domain description, rather than serializing the actual data instance. Assertions and comments remain unchanged.
