feat: buy, sell and info for Raydium LaunchLab coins

A mint with no pump.fun curve is looked up on LaunchLab, under any launchpad's
platform config and any quote asset, with Token-2022 transfer fees counted.

 **Error handling:** `error()` raises `SystemExit` — code after it is unreachable. Core functions return `dict` with `"error"` key for expected failures (graduated tokens, not found, slippage exceeded, insufficient_balance). Catch `ValueError` for wrong wallet password in every command that decrypts. Buy/sell functions perform pre-trade balance validation — SOL for fees and rent, the quote asset for the spend, token balance for sells with specific amounts.
 
-**Auto-routing:** When `buy_token` / `sell_token` returns `{"error": "graduated"}`, the command layer in `commands/trade.py` automatically retries via `buy_pumpswap` / `sell_pumpswap` (PumpSwap AMM). Never suppress or swallow the `"graduated"` error in core — the routing decision belongs in the command layer.
+**Auto-routing:** `_route` in `commands/trade.py` picks the venue from the errors core returns: `{"error": "graduated"}` from `buy_token` / `sell_token` retries on PumpSwap, `{"error": "not_found"}` retries on LaunchLab (`buy_launchlab` / `sell_launchlab`). Never suppress or swallow those errors in core — the routing decision belongs in the command layer. `info` falls back to LaunchLab the same way in `core/info.py`.
