-Add `nansen research` command with 11 subcommands for historical/point-in-time analytics: dex-trades, pnl-leaderboard, token-flow-summary, token-quant-scores, top-holders, who-bought-sold, smart-money-balances, token-screener, wallet-balances, tx-lookup, wallet-transactions. Labels and metrics resolve at the requested date rather than current state — useful for backtesting and historical research.

-`research historical-token-flow-summary` now errors immediately when `--page` or `--limit` are passed (the endpoint returns a single aggregated row and does not support pagination). `research historical-smart-money-balances` now errors when `--sort` or `--order-by` are passed (the endpoint does not support ordering). Previously both flags were silently dropped.
