-- Convert naive timestamps to timestamptz.
-- Existing values were written as session-local wall clocks (via now()/defaultNow)
-- or occasionally as UTC components (drizzle mapToDriverValue toISOString).
-- Interpret stored values in the current session TimeZone so local wall-clock
-- rows (the common path for messages) keep the same absolute instant.
--
-- Drizzle reads naive `timestamp` as UTC (textToDateWithTz), which shifted
-- displayed times by the server offset (e.g. -5h in America/Chicago).
