0.8.0

• Added photo-picker reference — PHPickerViewController vs deprecated UIImagePickerController library mode (~2× slower to present, every time, and requires photo permission PHPicker doesn't need), camera-mode exception, background-queue delegate callback trap, load-failure vs remove-image contract.
• Disambiguated overlapping Topic Router row families — animation (animation / implicit-animations / compound-cell-row-animation), testing (testing-principles / testing), sizing (self-sizing / step-transition-sizing / popover-tooltip): each row now carries a scope discriminator and NOT-for cross-pointers; added a family rule requiring boundary declarations on both parent and child rows.
• Expanded cloud-backup-providers — remote-status display (list authority, stale-while-revalidate, display cache), advisory contents manifest, cache invalidation and manifest stale-drop honoring list authority and upload failure.
• Documented composer idempotent bootstrap rule for recreated detail controllers.
• Documented signing rules for installable builds — makefile run-installed builds must stay signed (keychain -34018), and xcodebuild-error-detection CODE_SIGNING_ALLOWED=NO must never touch installable builds.
