//! Per-connection context shared across middleware layers. Mirrors
//! charmbracelet/ssh.Context — a place to stash request-scoped values that
//! outlive a single middleware frame.
//!
//! Phase 0 keeps this minimal: just the auth state and a small kv map.
//! Public-key, certificate, and cancel-channel surface land alongside the
//! middleware framework in Phase 2.
