New futures_quote(commodity, delivery?) tool wraps the new /api/data/futures
endpoint: reports latest price, today's session open, prior settle, and both
moves (since open and on the day). With a delivery month it resolves the listed
contract; without it, the continuous nearby. Adds client.futures(), fmt_futures(),
tests, and a CHANGELOG entry.

Document the new basis_movement/basis_detail tools, the flexible price_history
and latest_prices signatures, and the /api/data/history commodity-optional
change, with example question→call mappings.
