Add Bitquery Hyperliquid API to APIs & Tools

[divyasshree-BQ]

Adds Bitquery's Hyperliquid API to the APIs & Tools section.

The reason it may be worth a slot here rather than being another API wrapper: Bitquery serves Hyperliquid's order book at L3 (market-by-order) market-wide. Every book delta is a single order carrying its own order id and the wallet address that placed it.

	Hyperliquid native l2Book	Bitquery BookUpdates
Grain	L2 — total size per price level	L3 — one event per individual order
Depth	5-20 levels	unlimited
Attribution	none	order id + trader address

The native API does expose order-level detail, but only for your own account (orderUpdates, userFills); market-wide it serves aggregated L2. Because Hyperliquid settles on a transparent L1, the wallet behind each order is public — so this is L3 with named attribution, which does not exist on centralised venues, where exchanges anonymise L3 feeds. It makes market-maker tracking and cancel-to-fill analysis possible at all.

Beyond the book: trades, OHLCV candles, liquidations, per-trader funding, positions, leverage updates, TWAPs, mark prices, price updates and raw signed actions. The same query runs as a historical query or a real-time subscription, and the archive shares one protobuf schema with the Kafka streams, so backtest and production code decode identically.

Happy to reword or move it to Analytics if that fits the list better.
