google-labs-jules[bot] 5d6a6ef47b This commit addresses the "Stabilize non-linguistics tests and interfaces" task from TODO.md.
The main changes are:
-   Refactored the `Copyright` and `Monetization` relationships to use explicit join tables for each owning model, as per the "Option A" strategy. This fixes the GORM migration issues related to polymorphic many-to-many relationships.
-   Created new join table structs (e.g., `WorkCopyright`, `AuthorCopyright`, `WorkMonetization`, etc.).
-   Updated the domain models to use standard `gorm:"many2many"` tags with the new join tables.
-   Refactored the `CopyrightRepository` and `MonetizationRepository` to use the new association-based logic.
-   Updated the application services (`CopyrightCommands`, `CopyrightQueries`, `MonetizationCommands`, `MonetizationQueries`) to use the new repository methods.
-   Consolidated all repository interfaces into a single `internal/domain/interfaces.go` file for better code organization.
-   Added extensive integration tests for the new repository and application layer logic for `Copyrights` and `Monetizations`.
-   Fixed the deletion logic for `WorkRepository` to correctly handle cascading deletes with SQLite.
-   Updated the `TODO.md` file to mark the "Stabilize non-linguistics tests and interfaces" task as complete.
