Follows the same pattern as AppIcon-Debug (orange DEV banner) but with a purple banner and "NIGHTLY" text. The nightly CI workflow now passes ASSETCATALOG_COMPILER_APPICON_NAME=AppIcon-Nightly to xcodebuild so the nightly app gets its own distinct icon. Includes scripts/generate_nightly_icon.py for regenerating the icons from the production AppIcon source files.
