New: SQLite persistence layer (with JSON fallback)

• src/polymarket/sqliteStore.ts: all state now persists into a single data/zinger.db (WAL) via Node 22's built-in node:sqlite — no native compilation. Keyed by the JSON store's relative path, with one-time auto-migration of legacy JSON files.
• ml/sqlite_store.py + wiring in train_lstm.py, pipeline.py, export_onnx.py: Python scripts share the same docs table as the Node app, keeping both sides in sync.
• Fallback: node:sqlite is loaded via createRequire, so the package still runs on Node 20/21 — persistence.ts transparently falls back to JSON files when the built-in is unavailable.

Python/ML tooling (PR #1)

• Python binary resolution priority: ZINGER_ML_PYTHON → root .venv → ml/.venv → /usr/bin/python3.
• ONNX models load from <ROOT>/data/ml/models/onnx (overridable with ZINGER_ONNX_DIR).
• train_lstm.py: resume from checkpoint + --force retrain.
• New pyproject.toml / uv.lock for reproducible Python envs.
• Default RPC: https://1rpc.io/matic.

Frontend (PR #1)

• PolyDashboard.tsx: toggles for the paper/live strategy flags (poc, hedging, kelly, confidence, train-on-live).
