feat(websocket): ride alkcall 0.5.0 — OpenableAlpn establisher + timeout (ADR-049 Unit 3)
Mechanical pass for the alkcall 0.5.0 bump (review 006 sequencing:
ADR-049 → alkcall 0.5.0 → alkhttp mechanical pass):
- bump alkcall 0.4 → 0.5 (gateway feature unchanged)
- OpenableAlpn gains establisher: Option<OpenEstablisher> and
establisher_timeout: Option<Duration> (both default None via
OpenableAlpn::new — existing constructions compile unchanged) plus
a with_establisher(establisher, timeout) builder
- the install_channel_zero ferry calls
register_openable_with_establisher, threading both fields through
- docs updated (websocket.md, adapter.rs doc comments)
The alkcall 0.5.0 open_channel error-type change (ADR-049 §4) needs
no change here — this crate never calls open_channel (from_wss uses
ChannelClient::from_connection only).
Verification: cargo test (454 passed), cargo test --all-features
