Added a new `Linux News: LWN` screen that pulls current stories from the LWN homepage and presents them as readable, TV-friendly pages in the forecast rotation.
- added `/api/linux-news` to fetch `https://lwn.net/` and parse homepage headlines, blurbs, and article links
- created a new `linuxnews` display module, EJS partial, and SCSS styling
- paginated the LWN feed into 4 screens with 2 stories per page and enabled the display by default
- registered the new screen in the main display deck and included it in the startup/progress screen list
- tightened the story card layout to prevent page bleed and overlapping text between stacked pages
- shortened LWN blurbs and reduced headline/body typography so long top-slot stories fit cleanly inside the 512x250 content box
