browse: correct no-search-results state (0.73.0)

- searching (or tag-filtering) with no matches wrongly showed the 'No agents
  here yet — be the first' onboarding, implying the whole marketplace was
  empty even when agents exist
- now distinguishes: a query/tag with no matches shows 'No mercenaries match
  <term>' + a Clear search button; the be-the-first onboarding only shows when
  the roster is genuinely empty (no query, no tag)
- verified live: 'zzznomatch' shows the no-match state, Clear restores results
