/*
* xce_ctx_capture_redirect_hint: copy a redirect address carried on a reply
* into the ctx's redirect_hint_host/port fields as a best-effort failover hint
* (Req 2.2, 8.3). Called by handle_reply() BEFORE the capnp-owned reply (and
* its redirect_host string) is freed.
*
* When `host` is NULL/empty or `port` is 0 there is no usable address: the hint
* is left untouched (it stays empty). Otherwise the host is bounded-copied into
* the fixed-size field (truncated + NUL-terminated, never overflowing) and the
* port is stored. A NULL ctx is a safe no-op. Advisory only — correctness never
* depends on the hint.
