Improve mule classifier: native-NaN + missingness (CV PR-AUC 0.88->0.91, recall 13->15/16)

Add mule-ring detection (novelty) + new dark pitch deck

Harden HF sync workflow: LFS push, concurrency guard

Redesign dashboard: fraud-ops command-center UI (dark, signal-coded)

Fix HF Space config: YAML frontmatter must be first line of README

Add deploy script, Docker Space, CI auto-sync, live-scoring tab

MuleGuard: end-to-end mule-account detection + HF Space deploy
