feat: full clean architecture refactor — domain → application → infrastructure → presentation

- Restructure from Modular MVC to Clean Architecture with 4 strict layers - Domain: entities (anime/komik/proxy), Repository traits, typed errors - Application: use case classes with proper error propagation - Infrastructure: repository impls, parsers, Redis cache, HTTP/scraping, browser - Presentation: Axum handlers, DTOs, AppState, router, AppError+IntoResponse - Migrate all parsers (otakudesu, alqanime, komik) to native infra implementations - Replace once_cell::sync::Lazy/OnceCell with std::sync::LazyLock/OnceLock - Remove 150+ old files in modules/ and shared/ directories - Remove once_cell from Cargo.toml dependencies - Fix test/debug binaries to use new import paths - Zero new clippy warnings Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
