Fix nil pointer crashes, improve staged write reliability, and enhance external cache consistency.

The filesystem experienced critical nil pointer dereference crashes during concurrent flush operations. Staged write mode was unreliable, often failing to complete flushes to remote storage, leading to potential data loss. Additionally, the external caching layer was underutilized and inconsistent, resulting in suboptimal performance and throughput. This PR addresses these issues by adding robust nil checks, implementing comprehensive retry and error handling for staged writes, and enhancing cache logic with proactive hash discovery and smart fallback mechanisms.

This commit adds nil checks to prevent nil pointer dereferences in the file handling logic. The checks are added before calling Broadcast() on readCond, which was the source of the panic. The fix is verified through code analysis, logic proof, and integration tests.
