Introduces an opt-in EnableBigIntEvents flag on StoreOptions.Events that switches the mt_quick_append_events PostgreSQL function to use bigint types for event version, sequence, and return values. This prevents integer overflow when sequence values exceed the ~2.1 billion int32 limit. The flag defaults to false for backward compatibility and will become true by default in Marten 9.0. Includes 6 tests verifying behavior with the flag both enabled and disabled, and documentation in the event store configuration guide.
