1.13.0: mempool channel for pending Hyperliquid transactions - #21
Merged

Conversation
…(1.13.0) - ws::MEMPOOL_CHANNEL, served only at ws::STREAM_WS_URL; the symbol is optional on it. ws::DEFAULT_WS_URL names the default endpoint. - MempoolItem and MempoolSignature, decoded with ServerMsg::mempool_items() or MempoolItem::decode(). - Capability::ws_endpoint and Capability::plans. - Version 1.13.0.
- MempoolItem::action is a Box<RawValue> holding the action as sent, key order included; action_value() parses it for inspection. - Mempool frames arrive as ServerMsg::Mempool, read from the frame text by ServerMsg::from_text(), which the client now uses for every message. - serde_json's raw_value feature is enabled.
- A capability row without ws_endpoint is served at the default endpoint, wss://api.0xarchive.io/ws; without plans, on every plan. - The unfiltered stream carries the pending transactions our node receives, and pending transactions are never stored. - The parsed action may not keep the original key order; the raw action does.

Adds the
