host: relate removes just the picked candidate row in place (no reload)
Picking a candidate to relate it no longer does a full POST -> 303 -> reload.
The candidate <li> now carries an id and its relate form is an AJAX sx-post
(sx-target="#cand-<kind>-<other>", sx-swap="delete"): on success the engine
deletes just that one row — the item is now related, so it leaves the candidate
pool with no reload and no candidate-list refetch. host/blog-relate-submit returns
an empty 200 for an SX request (so the delete swap fires) and still 303s for a
plain POST (no-JS fallback via the form's method+action).

relate-picker.spec.js test 4 updated to assert the in-place row delete + no reload
+ the relation still persists (shows on the post page). 6/6 + conformance 272/272.

(Symmetric unrelate-in-place was prototyped but backed out: the current-links
form, bound via boot's process-elements rather than post-swap, didn't fire the
AJAX delete despite identical markup — a binding quirk to chase separately. Unrelate
keeps its plain POST -> reload for now, no regression.)

// Browser check for the relate picker (lib/host/blog.sx). Runs against an
// ephemeral host server seeded with a host post + 25 candidates by
// run-picker-check.sh, which copies this spec into the Playwright env and sets
// SX_TEST_URL. The picker is a DECLARATIVE SX-htmx form (no client JS): the form
// GETs /<slug>/relate-options on "load" and on a debounced "input", swapping the
// results <ul>; a full page carries a "load more" sentinel that pages on reveal.
// Exercises the login redirect, the initial populate, debounced filter, infinite
// scroll, click-to-relate, AND populate after a boosted SPA nav (the case the old
