feat(ton-trading-bot): add 15 algorithmic trading tools (v2.0.0)

[konard]

Summary

Fixes #43. Expands ton-trading-bot from 6 to 21 atomic tools covering all requested algorithmic trading categories, following the same architecture (LLM composes atomic tools into strategies).

P0 — Cross-DEX Arbitrage

• ton_trading_get_arbitrage_opportunities — compares prices across StonFi, DeDust, TONCO, swap.coffee; returns opportunities sorted by net profit after fees

P0 — Sniper Trading

• ton_trading_get_token_listings — fetches recently-listed tokens via GeckoTerminal, filtered by liquidity floor
• ton_trading_get_token_info — price, market cap, FDV, 24h volume for any token address
• ton_trading_validate_token — risk score + warnings (low liquidity, low volume, wash-trade signals)

P0 — Copy Trading

• ton_trading_get_top_traders — scans trending pools for wallets ranked by win rate
• ton_trading_get_trader_performance — analyses a wallet's on-chain swap history via tonapi.io

P1 — Liquidity & Farming

• ton_trading_get_active_pools — lists pools sorted by 24h volume, filterable by DEX
• ton_trading_get_farms_with_apy — estimates APY from fee yield × 365, sorted descending
• ton_trading_get_pool_volume — 1h/6h/24h volumes, price changes, and buy/sell counts for a pool

P1 — Backtesting

• ton_trading_backtest — replays buy_and_hold, mean_reversion, or momentum strategy against journal history; returns win rate, PnL, max drawdown, and Sharpe ratio

P2 — Risk Management

• ton_trading_calculate_risk_metrics — VaR (configurable confidence), max drawdown, Sharpe, profit factor from closed trades
• ton_trading_set_stop_loss — registers stop-loss / take-profit rules in the journal DB
• ton_trading_get_optimal_position_size — Kelly Criterion + fixed-fraction sizing from historical win rate

P2 — Automation

• ton_trading_schedule_trade — stores a pending trade for future execution (validated future ISO datetime)
• ton_trading_get_scheduled_trades — lists pending trades, flags which are due for execution

Implementation notes

• migrate() adds two new tables: stop_loss_rules and scheduled_trades
• manifest.json bumped to v2.0.0 with all 21 tools listed
• All external API calls use AbortSignal.timeout(15_000) per patterns.md
• Caching via sdk.storage with appropriate TTLs (30s–5min per data freshness)
• No strategy logic embedded — all decision-making remains with the LLM

Test plan

• All 78 unit tests pass locally (node --test plugins/ton-trading-bot/tests/index.test.js)
• No new lint errors (existing warnings in other plugins are pre-existing)
• 50 new test cases added covering all 15 new tools
• Existing 28 tests continue to pass unchanged
