Subject: [PATCH] fix(gateway): pass max_total_size_mb and max_file_size_mb to
 CheckpointManager

The /rollback command handler in gateway/run.py was constructing
CheckpointManager with only enabled and max_snapshots, omitting
max_total_size_mb and max_file_size_mb that the __init__ expects.
This caused a TypeError on every /rollback invocation when checkpoints
were enabled.

Fixes: NousResearch/hermes-agent#18841
