Replace Spring Retry CircuitBreakerRetryPolicy with lightweight custom implementation using ConcurrentHashMap and AtomicReference<Instant>. Avoids classpath conflict between spring-retry and spring-aspects RetryTemplate, and eliminates stacked retries with Feign @Retryable. Behavior: circuit opens for 30s after first failure, returns fallback immediately without hitting external APIs. Transitions through CLOSED -> OPEN -> HALF_OPEN -> CLOSED automatically. Applied to AniListService and MyAnimeListService for all searchMangaByTitle, getMangasByTitle, and getMangaDataById calls.
