Improved multi-tab Zotero checks with faster parallel searches, visible queue progress, and safer recovery if Zotero stops during a check.

New:
- Shows a PDF indicator next to the title when a matched item has a PDF attachment (can be toggled off)
- Optional search across Zotero Group Libraries (off by default)
Fixed:
- Fixed a false-positive match when DOI is available but the title-search fallback picked an unrelated item
- Fixed the overlay not refreshing when rechecking without a cache
