fix: Corregir force unwraps y mejorar seguridad del código

- ManhwaWebScraper.swift: Eliminar force unwrap en URL con guard let
- ManhwaWebScraperOptimized.swift: Eliminar 2 force unwraps en URLs
- StorageServiceOptimized.swift: Usar .first en lugar de subscript [0]
- ImageCache.swift: Usar .first en lugar de subscript [0]
- Agregar caso invalidURL a ScrapingError enum

Build exitoso para iOS 15.0+ (simulador y device)
IPA generado y listo para sideloading

+/// Scraper que utiliza WKWebView para extraer contenido de manhwaweb.com.
+///
+/// `ManhwaWebScraper` implementa la extracción de datos de sitios web que usan
+/// JavaScript dinámico para renderizar contenido. Esta estrategia es necesaria
+/// porque manhwaweb.com carga su contenido mediante JavaScript después de la
+/// carga inicial de la página, lo que impide el uso de HTTP requests simples.
+///
+/// El scraper utiliza un `WKWebView` invisible para cargar páginas, esperar a que
+/// JavaScript termine de ejecutarse, y luego extraer la información mediante
+/// inyección de JavaScript.
+///
+/// # Example
+/// ```swift
+/// let scraper = ManhwaWebScraper.shared
+/// do {
+///     let manga = try await scraper.scrapeMangaInfo(mangaSlug: "one-piece_1695365223767")

+/// Cliente de API para comunicarse con el backend VPS.
+///
+/// `VPSAPIClient` proporciona una interfaz completa para interactuar con el backend
+/// que gestiona el almacenamiento y serving de capítulos de manga en un VPS.
+///
+/// El cliente implementa:
+/// - Request de descarga de capítulos al VPS
+/// - Verificación de disponibilidad de capítulos
+/// - Listado de capítulos descargados
+/// - Obtención de URLs de imágenes
+/// - Eliminación de capítulos del VPS
+/// - Consulta de estadísticas de almacenamiento
+///
+/// Usa URLSession con async/await para operaciones de red, y maneja errores
+/// de forma robusta con tipos de error personalizados.
+///
+/// # Example
+/// ```swift
+/// let client = VPSAPIClient.shared
+///
+/// // Solicitar descarga
+/// do {
+///     let result = try await client.downloadChapter(
+///         mangaSlug: "one-piece",
+///         chapterNumber: 1,
+///         imageUrls: ["https://example.com/page1.jpg"]
+///     )
+///     print("Download success: \(result.success)")
+/// } catch {
+///     print("Error: \(error)")
+/// }
+///
+/// // Verificar si está descargado
+/// if let manifest = try await client.checkChapterDownloaded(
+///     mangaSlug: "one-piece",
+///     chapterNumber: 1
+/// ) {
+///     print("Chapter downloaded with \(manifest.totalPages) pages")
+/// }

+/// 2. Preloading de páginas adyacentes (BEFORE: Carga bajo demanda)
+/// 3. Memory management para imágenes grandes (BEFORE: Sin control de memoria)
+/// 4. Optimización de TabView con lazy loading (BEFORE: Cargaba todas las vistas)
+/// 5. Thumbnail system para navegación rápida (BEFORE: Sin thumbnails)
