fix(docs): add release date for DataLab version 1.0.3

Fix: Move run_with_env() before freeze_support() for PyInstaller comp…

…atibility

The run_with_env() function must be defined before multiprocessing.freeze_support()
to ensure proper pickling in frozen executables. When defined after freeze_support(),
PyInstaller cannot properly register the function for multiprocessing, causing
"Can't get attribute 'run_with_env'" errors in worker processes.

This fixes the issue where isolated process computations hang in frozen builds
while working correctly in standard Python distributions.

Fixes isolated process execution in PyInstaller-built DataLab v1.0.2+
