The old adapter called `search.smzdm.com/ajax/?c=<channel>&s=<q>` which
now returns 404. This caused opencli smzdm search to always return empty
results regardless of keyword.
Fix: navigate directly to `search.smzdm.com/?c=home&s=<keyword>&v=b`
and scrape the rendered DOM via querySelectorAll('li.feed-row-wide').
Also switched from async IIFE to sync IIFE since all data is already in
the DOM after page load — no fetch needed.
Tested: opencli smzdm search --keyword A7M5 returns correct results
with prices and mall names.
