v1.3.0

Added

• Right-click send now offers a toast to narrow the send to the pointed image. (#3)

Changed

• Direct file sends carry the page URL, recorded as the item's source. (#3)
• Chooser thumbnails load the smallest advertised variant; videos load only once visible.
• The supported site list is cached, so the first send after idle no longer waits on it.

Fixed

• Batch sends from the chooser now say why they failed, not just a count.
• A revoked host permission is reported as such, not as a connection failure.
• Test connection pairs the token only with the saved origin and refuses malformed URLs.
• The chooser says when a page could not be scanned instead of "no images found".
• Scans keep lazy-loaded images whose real size is only advertised in srcset.
• The chooser and popup no longer offer file types monloader declines.
• Picking another resolution after a blocked preview restores the preview.

Thanks to @gary-host-laptop for the suggestions (#3)
