v0.4.7 — Spot+Perp Funding Arb + Lighter Spot Trading

Features

• Spot+Perp funding arb: scan, auto-exec for spot-hedged funding strategies
• Spot adapters for Hyperliquid and Lighter (buy/sell/balance/markets)
• Cancel by orderId alone — auto-detect symbol from open orders
• Skill scripts: arb-monitor, funding-analysis, preflight, spot-perp-scan, validate-arb

Fixes

• HL/Lighter decimal precision — official rounding, no silent fallback
• Lighter spot trading — accurate decimals, USDC transfers, nonce collision
• Post-execution fill verification for spot-perp entry/close
• Spot/perp balance check before spot-exec
• SDK parity — use API-provided values instead of re-deriving
• HL cancel/side bugs, Lighter empty trades
• Lighter API key index 2→4 (0-3 reserved)
• Move live API tests to integration/ to fix CI

Testing

• 965+ unit tests passing
• Spot adapter cross-validation tests (live)
