token_tracker.py — Pipeline Token Budget Tracker

Real-time token spend tracking across all pipelines with:
- SQLite store for token usage per pipeline/worker/hour
- CLI dashboard with live refresh
- Budget alerts at 50%, 80%, 100%
- Daily summary reports

Usage:
    python3 token_tracker.py --watch              # Live dashboard
    python3 token_tracker.py --summary            # Daily summary
    python3 token_tracker.py --record pipeline worker tokens  # Record usage
    python3 token_tracker.py --budget pipeline 200000000      # Set budget
    python3 token_tracker.py --alerts             # Check alerts
