Fix folder search navigation and add visible filter status badge

Navigation fix (root causes, not workarounds):
- Same file + filter active: clear filter then navigateTo — no re-open
- File in another tab: switchToTab, clear any restored filter, navigateTo
- File not open: loadFile (clears filter on fresh open) then navigateTo
- Replaced goToLine (sync, no cache warming) with navigateTo (async,
  pre-warms cache before scroll — eliminates blank-line flash)

Filter indicator:
- Status bar now shows a yellow "⊘ Filtered: N lines" pill when a filter
  is active, with an × button to clear it immediately
- Replaces the subtle "(N filtered)" text that was easy to miss
