Fix "Codex cannot access its local database" / "migration 1 was previously applied but has been modified" / "timed out waiting for state db backfill after 30s" on Codex Desktop (Windows/WSL/Mac/Linux) after the 0.130 → 0.131 update. CRLF/LF sqlx checksum drift in state_5.sqlite + logs_2.sqlite. Sessions preserved. See openai/codex#23787.
