glm-5.3-flash a80f9948b8 feat(build): feature-sided builds — server/client sides independently selectable (ADR-039 Amendment 1)
Split the feature graph so consumers pulling only the import adapters
(from_openapi / from_jsonschema / from_mcp) no longer compile the axum
/ hyper server stack, and server-only deployments no longer compile
reqwest. One crate, one import path — sides cut by features, not by a
crate split.

Feature graph:
- server (default): axum host, gateway, WS upgrade, to_openapi, to_mcp
- client (default): client host, forward, from_jsonschema, from_openapi
- openapi: shared OpenAPISpec model (implied by both sides)
- mcp: from_mcp needs client, to_mcp needs server
- wss: tungstenite transport (from_wss); tungstenite half of the
  shared WS↔byte-stream adapter
- h2/http1: hyper protocol features; imply server

Wire-contract neutral: gateway endpoints, ALPNs, and all public API
shapes unchanged; defaults keep both sides on.

Supporting changes:
- forward.rs drops its axum::body::Bytes type leak (bytes crate types)
- bounded_join + error-echo caps move to input_validation (usable by
  both sides; openapi_spec no longer imports from forward)
- byte_adapter: axum flavor compiles under server, tungstenite under
  wss; the generic pumps stay shared (WS-11)
- input_validation / openapi_spec import-only internals gated to the
  side that consumes them
- http-body-util moves to dev-dependencies (was test-only)
- integration-test required-features updated for the new sides
- from_wss unit tests (axum producer harness) gated to server

Verified: cargo test (defaults, 453) and --all-features (575) pass;
lean side builds (client / server / client,mcp / client,wss /
server,wss / openapi-only) build clean with zero warnings;
clippy -D warnings clean across all feature combinations; fmt clean.

//! alkhttp: HTTP interface for the alk stack — serves HTTP/1.1 + HTTP/2 on
//! standard ALPNs (with WebSocket upgrade carrying the channels protocol)
//! and hosts the HTTP-backed call-protocol adapters.
//!
//! # Feature sides
//!
//! The crate serves two independent use cases, selectable via features:
//!
//! - `server` — the producer side: the axum `Router` host
//! ([`server`]), the gateway routes ([`gateway`]), the WebSocket
//! upgrade path ([`websocket`]), `to_openapi`, and `to_mcp` (with
//! `mcp`).
//! - `client` — the consumer side: the shared outbound client host
//! ([`client`]) and the import adapters (`from_jsonschema`,
//! `from_openapi`, `from_mcp` with `mcp`).
//!
//! Both default on; lean builds take `default-features = false` with
//! the side they need. The shared OpenAPI document model rides behind
//! `openapi` (implied by both sides); `openapi_spec` and `to_openapi`
//! compile with it alone.
//!
//! # Documentation gate (HY-02)
//!
//! Public-API items must be documented: this crate is pre-crates.io and
//! docs.rs renders straight from the rustdoc. The deny below keeps the
//! gate from regressing.
