Changelog: - forward download progress from background/offscreen workers to content frames - add progress UI and button state management in Safari Books page script - emit structured progress callbacks and faster image fetching in SafariBooksDownloader - sync Firefox bundle with progress plumbing and concurrency improvements - ignore packaged extension archives Description: Expose progress events through the downloader so the content script can present real-time status, including chapter and asset fetching milestones. Added concurrency controls, page detection, and packaging telemetry, while keeping Firefox build behavior in sync and ignoring generated .xpi bundles.
