CRITICAL FIXES: - P0-1: Fix EPG N+1 query storm with batch loading * Implement XtreamServiceMobile with getBatchEPG() method * Batch load EPG data instead of per-channel requests * Reduce 50-200 concurrent requests to 1 request per category * Add EPG cache with 1-hour TTL to prevent redundant calls - P0-2: Remove destructive cache clearing on startup * Implement TTL-based cache invalidation * Preserve cache between app launches (6h channels, 1h EPG, 30m search) * Add HiveService.invalidateExpiredCache() method * Expected: -80% startup time on cold launches - P0-3: Preserve tab state with IndexedStack * Replace switch statement with IndexedStack * Keep all tabs alive in widget tree * Preserve scroll position, search state, filters across tab switches * Expected: instant tab switching (<100ms) HIGH PRIORITY FIXES: - P1-1: Debounce search input (500ms) * Prevent per-keystroke full rebuilds * Add search debounce timer - P1-3: Fix double FocusNode disposal crash * Remove duplicate focus node disposal in native_player_screen.dart * Prevents StateError on player exit Expected impact: -75-80% perceived latency, instant tab switching, no OOM on startup.
