jedarden fe59fa9785 feat(pdftract-47e42): implement URL fragment routing for shareable links 
- Add #page=N URL fragment routing for shareable inspector links
- Support browser back/forward navigation via hashchange event
- Persist overlay toggle state in localStorage with error handling
- Add isUpdatingFragment flag to prevent double-render on hash updates
- Update thumbnail click handler to rely on updateFragment()
- Clamp out-of-range page numbers with console warnings
- Default to page 0 for invalid/non-numeric page numbers
- Add vector fixture provenance entries

Acceptance criteria:
- URL #page=14 on load → starts on page 14 ✓
- Navigate via next button → URL updates to #page=15 ✓
- Browser back button → URL and view update correctly ✓
- Bookmark with #page=14 → reopens to page 14 ✓
- Overlay toggles persist across page refresh ✓
- Out-of-range #page=999 → clamps to last page ✓
- Invalid #page=abc → defaults to page 0 ✓
