Changelog Entry

Description

This PR introduces a resizable sidebar with persistent width, improves sidebar resizing performance using requestAnimationFrame, and updates layout responsiveness across the application. The sidebar width is now stored in localStorage and reflected via a CSS variable, ensuring consistent appearance and usability. All related layout components have been updated to use the new sidebar width variable for better responsiveness.
For improved user experience, sidebar resizing is only enabled on desktop environments. Minimum and maximum sidebar widths are enfoced.

Added

Resizable sidebar functionality with persistent width (saved in localStorage)
requestAnimationFrame(rAF)-based throttling for smooth sidebar resizing
New Svelte store: sidebarWidth (default: 260)
Sidebar resizing is available only on desktop; disabled on mobile
Minumum and maximum sidebar width constraints (min: 220px, max: 480px)

Changed

Updated all layout and container components to use var(--sidbar-width) instead of a fixed width (260px)
Sidebar width styling updated for better responsiveness and max-width handling

Deprecated

None

Removed

Hardcoded sidebar width values in layout and container components

Fixed

Sidebar resizing performance and responsiveness issues

Security

No security-related changes

Breaking Changes

BREAKING CHANGE: Sidebar width is now controlled via a CSS variable and Svlete store, replacing previous hardcoded values. Custom styles or integrations relying on the old fixed width may require updates.

Additional Information

This PR imroves the user experience on both desktop and mobile by making the sidebar more flexible and responsive.
