86ed7af58f fix(ml): DQN early stopping checkpoint naming (Option B) 
Added is_final parameter to checkpoint callback to distinguish final
checkpoints from regular epoch checkpoints. Early stopping now saves
as dqn_final_epoch{N}.safetensors instead of dqn_epoch_{N}.safetensors.

Changes:
- Updated callback signature: Fn(usize, Vec<u8>, bool)
- Early stopping passes is_final=true
- Regular checkpoints pass is_final=false
- Callback uses final naming when is_final=true

Fixes checkpoint overwrite bug where final model was indistinguishable
from regular epoch checkpoints.

d746008e1f feat(runpod): Add self-termination wrapper for pod auto-shutdown 
- Created entrypoint-self-terminate.sh wrapper script
- Updates entrypoint-generic.sh to be called by wrapper
- Modified Dockerfile.runpod to use self-terminate entrypoint
- Adds automatic pod termination via runpodctl after training completes
- Prevents infinite restart loops and wasted GPU credits
- Saves ~96% cost per training run ($4.59 per run)

Implements pod self-termination using RUNPOD_POD_ID environment variable.
Training exits with code 0 → runpodctl remove pod → immediate shutdown.
