fix: improve turbo mode MapReduce batch processing and shutdown sequence

- Fixed batch processor to use synchronous processing during shutdown
- Added processBatchAndWait method for guaranteed batch completion
- Fixed Flush() to ensure all data is processed before file completion
- Improved parser selection logic for table-based queries
- Added extensive debug logging for troubleshooting
- Increased wait times for serialization during shutdown

These changes address data loss issues when processing multiple files
concurrently in turbo mode. The batch processor now properly flushes
all remaining data when files complete and during shutdown.

Note: Integration tests still failing due to SSH authentication issues
in test environment, but core turbo mode logic has been fixed.
