feat: Phase 5 — integration layer (analytics pipeline, production node v2, CLI) + 12 tests

Browse Source 
live/integrator.py (AnalyticsPipeline):
  Real-time pipeline: data → microstructure → signals.
  Accumulates book snapshots + trades, computes OBI, VPIN, microprice,
  spread, depth, trade imbalance, HFT regime, and emits composite
  signal with confidence and breakdown. Per-coin isolation.

live/node_v2.py (ProductionNode):
  Rebuilt production node integrating ALL Phase 1-4 modules:
  - REST data fetching (order book, mark prices, funding rates)
  - AnalyticsPipeline per coin for real-time microstructure signals
  - Treasury for position/capital/PnL/breaker management
  - ToxicityFilter integration via HlMakerPool makers
  - HlMakerPool for per-coin A-S quoting
  - CrossVenueMonitor, FundingBasisMonitor, LiquidationRiskOverlay
  - Paper trading with probabilistic fill simulation
  - Dashboard metrics JSON output (equity, treasury, analytics, maker)
  - Periodic status logging

cli.py (unified CLI):
  Subcommands integrating all modules:
    collect   — Run Hyperliquid data collector to Parquet
    analyze   — Run microstructure analytics on stored data
    simulate  — Run market-making simulator on stored data
    run       — Start production trading node (paper or live)
    backtest  — Run VectorBT backtest

12 integration tests (all pass):
  - AnalyticsPipeline: empty, book, trade, VPIN, emit, regime, isolation
  - ProductionNode: creation, tick cycle (3 ticks), metrics JSON output
  - CLI: import verification

Total test suite: 184 tests, all passing.
