Update the \timing command documentation to clarify that: - Query execution time is always measured regardless of \timing setting - \timing only controls whether timing information is displayed - The measured time is always available in LAST_QUERY_MS variable Add comprehensive documentation for the LAST_QUERY_MS variable: - Explains it contains execution time in milliseconds (3 decimal places) - Always updated after each query execution - Initialized to 0 at session start - Includes usage example for conditional logic This completes the documentation for the LAST_QUERY_MS feature.
