Struct InstrumentedWalWriter 

pub struct InstrumentedWalWriter<W: WalWriter> { /* private fields */ }

WAL writer wrapper that records authoritative append outcomes.

This wrapper preserves the underlying writer behavior and error propagation. It only records append success/failure totals after each append result is known. flush and close are transparent pass-through operations.
