Changes Made

1. crates/clawhdf5-agent/src/lib.rs -- Eliminate WAL unwrap() via is_none_or + if let

• Replaced two if self.wal.is_some() { ... self.wal.as_ref().unwrap()... } patterns
• New: self.wal.as_ref().is_none_or(|w| ...) + if let Some(ref mut w) = self.wal
• Eliminates 4 production unwrap() calls -- cannot panic now
