Function connect_pinned_with_resumption 

pub async fn connect_pinned_with_resumption(
    host: String,
    port: u16,
    pinned_key: Vec<u8>,
    hint: ResumptionHint,
    early_data: Vec<u8>,
) -> Result<Arc<PhantomSession>, CoreError>

Connect to a pinned server with a 0-RTT resumption attempt — the resumption-aware analogue of connect_pinned.

hint is a ResumptionHint from a prior session’s PhantomSession::resumption_hint; both of its fields must be exactly 32 bytes or the call fails with ValidationError before any socket is opened. early_data (≤ 16 KiB) is sealed into the resuming ClientHello so it reaches the server on the very first flight.

Acceptance is best-effort: when the server does not consume the early-data (stale/unknown ticket or AEAD failure) the handshake completes 1-RTT — the caller checks PhantomSession::early_data_accepted and re-sends over the normal channel when it is not Some(true).

Native-only, like connect_pinned: TcpSessionTransport lives behind cfg(not(target_arch = "wasm32")).
