Remove ~8000 lines of inline JavaScript styles from linker.js and organize
them into two focused stylesheets:
- linker-shell.css: modal shell, backdrop, window controls, layout structure
- linker-main.css: main content area (cards, buttons, forms, dialogs, tabs)
Simplify and clean up css-variables.css variable definitions.
Update css-loader.js to load both new stylesheet files.
Significantly improves code maintainability and separation of concerns.
