Description

Problem
I just discovered the hard way that BundleGen completely clobbers existing bundles, not only overwriting files, but deleting files it does not write (like training output).

Desired solution
It would be nice to have a clobber=True kind of option, where the default would be to give a warning that the bundle directory already exists.

Example code
Here are the relevant parts of what I ran:

from monai.apps.auto3dseg import BundleGen


bundle_generator = BundleGen(
    algo_path=work_dir,
    data_stats_filename=datastats_file,
    data_src_cfg_name=input_yaml,
)

bundle_generator.generate(work_dir, num_fold=5)

Research direction

Start by locating the Auto3DSeg BundleGen implementation and its generate(work_dir, num_fold=5) entry point. Reproduce the issue with an existing bundle directory containing unrelated training output, then verify that default handling warns instead of deleting it and that explicit clobber behavior is distinguishable.
