refactor(app): move composition root to main.go
Refactored the application's dependency injection and server setup to improve modularity and adhere to the Dependency Inversion Principle. - Moved the instantiation of all application services from `internal/app/app.go` to the composition root in `cmd/api/main.go`. - The `app.NewApplication` function now accepts pre-built service interfaces, making the `app` package a simple container. - Updated `internal/testutil/integration_test_utils.go` to reflect the new DI pattern, ensuring tests align with the refactored structure. - Corrected build errors that arose from the refactoring, including import conflicts and incorrect function calls. - Updated `TASKS.md` to mark the 'Refactor Dependency Injection' task as complete.

- [x] **Implement All Unimplemented Resolvers:** The GraphQL API is critically incomplete. All of the following `panic`ing resolvers must be implemented. *(Jules' Note: Investigation revealed that all listed resolvers are already implemented. This task is complete.)*
|
||||
- **Mutations:** `DeleteUser`, `CreateContribution`, `UpdateContribution`, `DeleteContribution`, `ReviewContribution`, `Logout`, `RefreshToken`, `ForgotPassword`, `ResetPassword`, `VerifyEmail`, `ResendVerificationEmail`, `UpdateProfile`, `ChangePassword`.
|
||||
- **Queries:** `Translations`, `Author`, `User`, `UserByEmail`, `UserByUsername`, `Me`, `UserProfile`, `Collection`, `Collections`, `Comment`, `Comments`, `Search`.
|
||||
- [ ] **Refactor API Server Setup:** The API server startup in `cmd/api/main.go` is unnecessarily complex.
|
||||
- [ ] Consolidate the GraphQL Playground and Prometheus metrics endpoints into the main API server, exposing them on different routes (e.g., `/playground`, `/metrics`).

### EPIC: Core Architectural Refactoring

|

- [ ] **Refactor Dependency Injection:** The application's DI container in `internal/app/app.go` violates the Dependency Inversion Principle.
|
||||
- [ ] Refactor `NewApplication` to accept repository *interfaces* (e.g., `domain.WorkRepository`) instead of the concrete `*sql.Repositories`.
|
||||
- [ ] Move the instantiation of platform components (e.g., `JWTManager`) out of `NewApplication` and into `cmd/api/main.go`, passing them in as dependencies.

|
||||
- [ ] **Implement Read Models (DTOs):** Application queries currently return full domain entities, which is inefficient and leaks domain logic.
|
||||
- [ ] Refactor application queries (e.g., in `internal/app/work/queries.go`) to return specialized read models (DTOs) tailored for the API.
|
||||
- [ ] **Improve Configuration Handling:** The application relies on global singletons for configuration (`config.Cfg`).
