host: relate/unrelate keep both lists in sync (add to current list, never blank the picker)
Two reported bugs on the edit page's relation editor:
 1. relating a candidate didn't add it to the current-relations list (the AJAX
    relate just deleted the candidate row; the relation only showed after a reload);
 2. removing a relation could blank the relate picker.

Fix (lib/host/blog.sx): both the candidate's relate form and a current relation's
remove form now target #rel-editor-<kind> with sx-swap=outerHTML, and the
relate/unrelate handlers return the re-rendered editor for that kind (current list +
a fresh picker). So one swap keeps BOTH lists in sync: the related post moves into
the current list and out of the (re-loaded) candidate pool; removing moves it back.
Gated on the SX-Target header, so a plain boosted form / no-JS POST (the is-a-tag
toggle) still redirects + re-renders #content.

Engine fix (web/orchestration.sx): handle-html-response's non-select branch called
post-swap on the OLD target, which an outerHTML swap has already REPLACED — so the
swapped-in content's triggers (here the re-rendered picker's "load") never bound and
the picker stayed empty. post-swap the swap result (the new node), mirroring the
sx-select branch. Recompiled orchestration.sxbc for the content-addressed client.

Tests:
 - web/tests/test-relate-picker.sx: relating re-syncs the editor (post in current
   list + picker re-loads); removing does likewise — both fail without the engine fix.
 - lib/host/tests/blog.sx: relate/unrelate return the re-rendered editor fragment
   (200, #rel-editor + picker), forms wire to #rel-editor-KIND/outerHTML, plain
   boosted POST still 303.
 - relate-picker.spec.js: the full in-page flow (relate adds to list, remove keeps
   the picker, no reload) + persistence.

Verified: host conformance 277/277, web engine suite 8/8, run-picker-check 3/3,
run-spa-check 3/3.

// 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.
//
// TRIMMED to the irreducibly-real-browser cases. The picker's interactive
// behaviours — populate-on-load, debounced filter, sentinel paging, relate→delete
// row, error/retry visible state — are now SX engine tests in
// web/tests/test-relate-picker.sx (they drive the SAME engine against a mock DOM,
// no Chromium). Its server contract + persistence are SX conformance tests in
// lib/host/tests/blog.sx. What remains here needs a live boosted-SPA browser:
// 1. a boosted form POST swaps in place (bind-boost-form regression), and
// 2. the picker re-binds its triggers on content brought in by a boosted SPA
// nav (the case an inline <script> picker silently failed).
