feat: scaffold crate with alkcall 0.1.1 dependency

Empty module tree (adapters, client, gateway, server, websocket) matching
the AGENTS.md subsystem map. Features: h2/http1 (default), mcp (rmcp),
wss (tokio-tungstenite, for the from_wss consumer adapter).

Verified: cargo check (default), cargo check --all-features.
