Upgrade to 1.0.0-rc785

Concerns: pushword/core

Image rights are now read from PNG, WebP and C2PA

If you ran pw:media:license on rc784, re-run it. Extraction went through Imagick::pingImage(), which exposes metadata profiles for JPEG only. Every PNG and WebP therefore read as carrying no rights whatever its XMP actually said, so a photographer's PNG could be recorded as seeded — the site's licence applied to somebody else's image, which is the one outcome this feature exists to prevent.

php bin/console pw:media:license --all --dry-run   # review what changes
php bin/console pw:media:license --all

--all is required: the media already carry a licenseState, and without it they are skipped. Media whose licence was asserted by hand are still never rewritten, so a real decision you made in the admin survives the re-run.

Two other changes come with it:

• C2PA manifests are read for digitalSourceType. A gpt-image PNG carries no XMP, no IPTC and no EXIF at all — only C2PA — so AI-generated images were not recognised as such. See Image license.
• ext-imagick is no longer involved in reading metadata; the containers are walked directly, which is also why the xmpReadable key is gone from the pw:media:license --format=agent JSON. Nothing to do unless you parsed that key.
