Updated ROADMAP.md to mark Phase 2 as completed and added detailed descriptions of completed tasks. Introduced three new value objects (`Base64String`, `TenantId`, and `PdfMetadata`) in the `DocumentOperator.Domain.Models.ValueObjects` namespace. These classes ensure type safety, immutability, and encapsulated validation. - `Base64String`: Handles Base64 string creation, validation, and conversion. - `TenantId`: Represents a tenant identifier with validation and normalization. - `PdfMetadata`: Represents PDF metadata with computed properties. Updated `DocumentOperator.Domain.csproj` to reflect the addition of these value objects. The project is now ready to begin Phase 3 (Infrastructure Layer).
