deps: bump tokio-tungstenite 0.24 -> 0.29 (replaces #13)

Dependabot opened #13 to bump tokio-tungstenite from 0.24 to 0.29 but
the bare-version bump fails to compile: WebSocketConfig became
#[non_exhaustive] starting with 0.27, so the existing struct-literal
construction

    let ws_config = WebSocketConfig {
        max_message_size: Some(MAX_MESSAGE_SIZE),
        max_frame_size: Some(MAX_FRAME_SIZE),
        ..WebSocketConfig::default()
    };

produces

    error[E0639]: cannot create non-exhaustive struct using struct expression

Switch to the builder-style setters that 0.29 exposes on the default
value. Semantics are unchanged; both fields still carry the
MAX_MESSAGE_SIZE / MAX_FRAME_SIZE caps from the original config and the
rest of the WebSocketConfig defaults are preserved by starting from
WebSocketConfig::default().

This supersedes #13 — same target version, plus the code change
Dependabot can't make on its own.
