glm-5.3-flash 674120ad72 feat(websocket): WsTimeouts request extension for WS pump knobs (WS-17)
- WsTimeouts { idle, write } request extension mirrors ChannelsPolicy:
  a deployment layers it on a WS route (bare-registry routes included)
  to set the pump knobs per route
- precedence: extension present replaces the router state entirely;
  absent falls back to SessionState (adapter-configured idle) and the
  crate default write window — a Default impl never clobbers the
  adapter-configured idle knob
- upgrade.rs module + handler docs now state the real defaults for
  bare-registry routes (60 s idle + 60 s write, 64-session semaphore,
  handler-private WsSessions) and the extension surface
- split_ws_to_bytes_idle_with_write exposes the WS-18 write window to
  run_channels_session; acceptance test drives a bare-registry route
  with a 150 ms extension idle window (1001 eviction observed)

Verification: scripts/verify.sh OK (343 passed), test-support suite
ok, clippy -D warnings clean, fmt clean

//! WebSocket subsystem: the browser bidirectional path
//! (ADR-067, `docs/architecture/decisions`).
//!
//! A WS session carries the **channels protocol**: the 8-byte chunk
//! header multiplexes N logical channels over the WS binary message
//! stream; channel 0 is pre-negotiated as `alk/call` and dispatched by
//! the shared `Dispatcher`. The WS↔byte-stream adapter (`byte_adapter`)
//! is the single seam between axum's WS and
//! alkcall's byte-oriented channels machinery — shared with the
//! `from_wss` consumer path ([ADR-070]).
