v0.96.1

Fixed

• Duplicate holiday entries after changing region — public and school holidays no longer appear multiple times once you switch the holiday region (e.g. from a country-wide selection to a specific state). Each holiday sync now replaces the entire cached set for that country and year, so stale entries from a previously selected scope are removed. Existing duplicates clear on the next sync (use "Sync now" in settings to trigger it immediately).
