What's new
- Selected inbox conversations now fetch their recent message history even when Dexie/IndexedDB cache persistence is disabled.
- Cache-disabled, preview-only chats no longer rely on an envelope-only refresh that can contain only the latest message.
Reliability
- Adds regression coverage for cache-disabled selected-thread loading, stale rapid-selection responses, and empty post-write IndexedDB re-read fallback.
- Adds no-PII telemetry for direct network apply and cache re-read fallback paths so future one-bubble reports are easier to classify.
