pre-deployment fixes for HF Spaces

Update Cell 1 & 2 with user-verified working versions

Bulletproof Cell 1: check .git dir, rm partial clone, correct REPO path

Fix REPO path: clone root is /content/kuchbhi not /content/kuchbhi/spindleflow-rl

Rewrite train_colab.py: clean cells, fix audioop-lts, log file, reward curve

Remove Colab notebook — using plain .py script instead

Fix Cell 1: skip audioop-lts on Python < 3.13 (Colab uses 3.12)

Add Colab notebook: 8 runnable cells, both secrets, log + curve

Final Colab training script: log file, fixed reward curve, 100k steps

Add HF Hub push cell + fix pip deps in Colab training script

SpindleFlow RL — periodic push + log persistence
