🦊 v6.5.6

Improved Sidebery behavior and visual consistency.
- Improved the smoothness of Sidebery expand and collapse animations while reducing layout cost.
- Fixed the search box bounce during expand and collapse animations, and aligned its width with the tab list below.
- Refined Split View support so only the web content area adjacent to Sidebery uses squared corners. The other split view pane now keeps rounded corners on all sides.
- Adjusted the close button and tree branch expand button positions when uc.flex.sidebery-allow-resizable-width is enabled in collapsed mode, reducing accidental clicks near tab icons.
- Fixed the tab panel in the navigation bar not expanding correctly in collapsed mode when uc.flex.sidebery-allow-resizable-width is enabled.
- Restored the missing top and side margins in Sidebery’s panel settings dialog when rounded web content margins are enabled.
Improved uc.flex.enable-rounded-web-content by synchronizing the bottom margin of sidebar panels with the web content area, keeping both areas visually aligned.

Native vertical tabs no longer show the resize splitter while collapsed. The splitter is now shown only when the sidebar is expanded, keeping the collapsed layout cleaner.

Fixed a regression introduced in v6.5.0 where pinned tabs could not wrap automatically when uc.flex.sidebery-allow-resizable-width and Lock Sidebery were enabled at the same time.
Fixed a regression introduced in v6.5.3 where the Sidebery new tab button showed shadow overflow on both sides.
