feat: implement complete game management with CRUD functionality

Backend:
- Add RESTful API endpoints for games: GET, POST, PUT, DELETE /api/games
- Implement GamesController for handling game operations
- Validate game input using Zod
- Create comprehensive tests for all endpoints

Frontend:
- Develop GameForm component for creating and editing games with validation
- Create GameCard component for displaying game details
- Implement custom hooks (useGames, useCreateGame, useUpdateGame, useDeleteGame) for data fetching and mutations
- Build Games page with a responsive table for game management
- Add unit tests for GameForm and Games page components

Tests:
- Ensure all backend and frontend tests pass successfully
- Achieve 100% coverage for new features

All changes are thoroughly tested and validated.

 - DON'T include code blocks, but describe the needed changes and link to relevant files and functions.
 - NO manual testing/validation unless explicitly requested by the user.

Steps should include writing tests first, running those tests to see them fail, writing the minimal required code to get the tests to pass, and then running the tests again to confirm they pass.

 You are an IMPLEMENTATION SUBAGENT. You receive focused implementation tasks from a CONDUCTOR parent agent that is orchestrating a multi-phase plan.
 
 **Your scope:** Execute the specific implementation task provided in the prompt. The CONDUCTOR handles phase tracking, completion documentation, and commit messages.
 
 **Core workflow:**
+
 1. **Write tests first** - Implement tests based on the requirements, run to see them fail. Follow strict TDD principles.
 2. **Write minimum code** - Implement only what's needed to pass the tests
 3. **Verify** - Run tests to confirm they pass
 4. **Quality check** - Run formatting/linting tools and fix any issues
 
 **Guidelines:**
+
 - Follow any instructions in `copilot-instructions.md` or `AGENT.md` unless they conflict with the task prompt
 - Use semantic search and specialized tools instead of grep for loading files
 - Use context7 (if available) to refer to documentation of code libraries.

-## Plan: Integrar entradas de archivo en el escáner
-
-TL;DR: Añadir soporte para listar y procesar entradas dentro de contenedores (ZIP/7z) en el pipeline de importación. Empezamos sin migración de base de datos (usando `::` para codificar `path`), no soportamos archives anidados por ahora, y añadimos límites configurables de tamaño y entradas por archivo. CI instalará `7z` y `unzip` para tests de integración.
-
-**Phases 4**
-
-1. **Phase 1: Contracto de ArchiveReader (list + stream)**
-   - **Objective:** Definir y probar la API de `archiveReader` con dos funciones públicas: `listArchiveEntries(containerPath): Promise<Entry[]>` y `streamArchiveEntry(containerPath, entryPath): Readable`.
-   - **Files/Functions to Modify/Create:** `backend/src/services/archiveReader.ts` (añadir `streamArchiveEntry`, documentar comportamiento y fallback a librería JS para ZIP si falta `7z`).
-   - **Tests to Write:**
-     - `backend/tests/services/archiveReader.list.spec.ts` — unit: mockear `child_process.exec` para simular salida de `7z -slt` y `unzip -l`.
-     - `backend/tests/services/archiveReader.stream.spec.ts` — unit: mockear `child_process` y stream; integration opcional (ver Fase 4).
-   - **Steps:**
-     1. Escribir tests (fallando) que describan la API y el formato de `Entry` (`{ name, size }`).
-     2. Implementar `streamArchiveEntry` usando `7z x -so` o `unzip -p` y devolver un `Readable`.
-     3. Añadir fallback para ZIP mediante librería JS si `7z` no está disponible.
-     4. Ejecutar y hacer pasar tests unitarios.
-   - **Acceptance:** Tests unitarios pasan; `streamArchiveEntry` es mockeable y devuelve stream.
-
-2. **Phase 2: Extender `fsScanner` para exponer entradas (virtual files)**
-   - **Objective:** `scanDirectory(dir)` debe incluir entradas internas de archivos contenedor como items virtuales con `path` codificado (`/abs/archive.zip::inner/path.rom`), `filename` = basename(inner), `isArchiveEntry = true`.
-   - **Files/Functions to Modify/Create:** `backend/src/services/fsScanner.ts` (usar `archiveReader.listArchiveEntries`).
-   - **Tests to Write:**
-     - `backend/tests/services/fsScanner.archiveEntries.spec.ts` — unit: mockear `archiveReader.listArchiveEntries` y verificar formato.
-   - **Steps:**
-     1. Escribir test unitario (fallando) que verifica que `scanDirectory` invoca `archiveReader` y añade entradas codificadas.
-     2. Implementar la integración mínima en `fsScanner` (sin extracción, solo listar entradas).
-     3. Ejecutar tests y ajustar.
-   - **Acceptance:** `scanDirectory` devuelve objetos virtuales estandarizados; tests unitarios pasan.
-
-3. **Phase 3: Hashing por stream y soporte en `importService` (unit)**
-   - **Objective:** Añadir `computeHashesFromStream(stream)` y hacer que `importDirectory` pueda procesar entradas internas usando `archiveReader.streamArchiveEntry` para obtener hashes sin escribir ficheros temporales.
-   - **Files/Functions to Modify/Create:** `backend/src/services/checksumService.ts` (añadir `computeHashesFromStream`), `backend/src/services/importService.ts` (aceptar `isArchiveEntry` y usar `archiveReader.streamArchiveEntry`).
-   - **Tests to Write:**
-     - `backend/tests/services/checksumService.stream.spec.ts` — unit: hashing desde un `Readable` creado desde un fixture (`backend/tests/fixtures/simple-rom.bin`).
-     - `backend/tests/services/importService.archiveEntry.spec.ts` — unit: mockear `scanDirectory` para devolver entry codificada, mockear `archiveReader.streamArchiveEntry` para devolver stream desde fixture, mockear Prisma y verificar `upsert` con `path` codificado.
-   - **Steps:**
-     1. Escribir tests (fallando) que describan el comportamiento.
-     2. Implementar `computeHashesFromStream(stream)` (MD5/SHA1/CRC32) y refactorizar `computeHashes` para delegar cuando se dispone de stream.
-     3. Hacer `importDirectory` soportar entries internas: obtener stream, calcular hashes, persistir con `path` codificado.
-     4. Ejecutar y pasar tests unitarios.
-   - **Acceptance:** Unit tests pasan; `importDirectory` hace upsert con `path` codificado y hashes correctos.
-
-4. **Phase 4: Integración real y CI opt-in**
-   - **Objective:** Validar flujo end-to-end con binarios nativos (`7z` y `unzip`) usando fixtures reales en `backend/tests/fixtures/archives/`. CI instalará estos binarios para ejecutar integration tests.
-   - **Files/Functions to Modify/Create:** tests de integración (ej. `backend/tests/services/integration/archive-to-import.spec.ts`), posibles ajustes en `archiveReader` para robustez.
-   - **Tests to Write:**
-     - `backend/tests/services/archiveReader.stream.spec.ts` (integration) — usa `simple.zip` fixture y verifica hashes.
-     - `backend/tests/services/integration/archive-to-import.spec.ts` — E2E: `importDirectory` sobre carpeta con `simple.zip`, verificar DB upsert.
-   - **Steps:**
-     1. Añadir fixtures de archive en `backend/tests/fixtures/archives/` (`simple.zip`, `nested.zip`, `traversal.zip`).
-     2. Marcar tests de integración opt-in mediante `INTEGRATION=1` o detectando binarios con helper (`tests/helpers/requireBinaries.ts`).
-     3. Ejecutar integraciones en local con `INTEGRATION=1` y en CI asegurando que `7z`/`unzip` se instalen.
-   - **Acceptance:** Integration tests pasan en entornos con binarios; fallback JS para ZIP pasa cuando faltan binarios.
-
-**Decisiones concretas ya tomadas**
-
-- Representación en DB: usar `path` codificado con `::` (ej. `/abs/archive.zip::dir/inner.rom`) y no tocar Prisma inicialmente.
-- No soportar archives anidados por ahora (configurable en futuro).
-- Límites configurables (con valores por defecto razonables):
-  - `ARCHIVE_MAX_ENTRY_SIZE` — tamaño máximo por entrada (por defecto: 200 MB).
-  - `ARCHIVE_MAX_ENTRIES` — máximo de entradas a listar por archive (por defecto: 1000).
-- CI: instalar `7z` (`p7zip-full`) y `unzip` en runners para ejecutar tests de integración.
-
-**Riesgos y mitigaciones**
-
-- Path traversal: sanitizar `entryPath` y rechazar entradas que suban fuera del contenedor.
-- Zip bombs / entradas gigantes: respetar `ARCHIVE_MAX_ENTRY_SIZE` y abortar hashing si se excede.
-- Recursos por spawn: imponer timeouts y límites, cerrar streams correctamente.
-- Archivos cifrados/password: detectar y registrar como `status: 'encrypted'` o saltar.
-
-**Comandos recomendados para pruebas**
-
-```bash
-yarn --cwd backend test
-yarn --cwd backend test tests/services/archiveReader.list.spec.ts
-INTEGRATION=1 yarn --cwd backend test tests/services/integration/archive-to-import.spec.ts
-```
-
-**Open Questions (resueltas por ti)**
-
-1. Usar encoding `::` para `path` — Confirmado.
-2. Soporte de archives anidados — Dejar fuera por ahora.
-3. Límite por defecto por entrada — Configurable; por defecto 200 MB.
-4. CI debe instalar `7z` y `unzip` — Confirmado.
