giles 98ff7a350a host/tests: Phase 2 — trim Playwright to a boot smoke
The picker's per-behaviour browser tests are now SX engine tests
(web/tests/test-relate-picker.sx) + SX conformance (lib/host/tests/blog.sx), so
delete them from Playwright and keep only what needs a real boosted-SPA browser:

  spa-check.spec.js (3): WASM kernel boots + loads modules CONTENT-ADDRESSED
    (/sx/h/{hash} fetches, zero path-.sxbc fallback — new assertion) + marks
    ready; a boosted nav fragment-swaps #content (raw! HTML path); back/re-boost.
  relate-picker.spec.js (2): the bind-boost-form remove button; the picker
    re-binds its load trigger on content brought in by a boosted SPA nav.

Net: 11 browser tests -> 5. Both ephemeral-host suites verified green
(run-spa-check.sh 3/3, run-picker-check.sh 2/2).
