Summary

This PR adds 4 new media bar display styles to match the core app. The media bar mode comes with the ability to change instantly, as well as syncs to the Moonbase plugin. It also comes with parallelization of API requests to get media bar items, which was necessary as startup time was negatively impacted initially.

Changes Made

New Features

• MakD Style: Blurred backdrop with lower quality image, centered layout, hidden info bg & overview text.
• Banner Style: Compact backdrop anchored at top, homeRows remain visible.
• Gallery Style: MarkupGrid component with 5 items per page, different style for narrow/wide content.
• Bookshelf Style: MarkupGrid component with dynamic items per page, centered and larger active item, random blendColor for book color.
• The new modes are able to be changed instantly, rather than requiring a restart of the app.

Refactoring

• applyMediaBarLayout(): Centralized media bar/home rows visibility and backdrop sizing/local into a single function in Home.bs, replacing 6 duplicated code blocks
• refreshDisplay(): Extracted mode-aware display refresh in MediaBar.bs, replacing duplicated code in onFocusChanged(), onVisibilityChanged(), refreshCurrentDisplay()
• startBackdropCrossfade(): Deduplicated backdrop crossfade logic into a single function in Home.bs
• buildBackdropUrl()/buildItemUrls(): Separated URL construction from processItem() to support mode switching without re-processing item data
• filterAndDedupeItems(): Moved filtering/deduping logic from MediaBar.bs in to MediaBarTask.bs for parallel processing

Performance

• Parallelized API requests: MediaBarTask.bs now fires concurrent async requests per library and collects results via message port. Necessary to keep app startup times within acceptance times after adding these new styles.
• Moved client-slide dedupe in to the task, freeing up the render thread.

Testing

• Tested syncing settings between an Android TV and this app, seems to work.
• Tested using BSProfiler and Roku Resmon to ensure the changes didn't negatively affect app performance.

Tried to cover as many edge cases that I could, but something may always slip through. I would appreciate if more people/testers could test switching between modes to identify issues I may have missed.

• Tested on physical Roku device
• Tested via sideload
• Manual testing completed
• Not tested (explain why):
