decius-css v0.6.2

Fixed

• Restored edge splitting for docked panel groups when dragging panel tabs or tearoffs onto a docked pane edge.
• Kept floating tearoff targets tab-only while allowing tearoffs to dock to the app/window left, right, top, and bottom edges.
• Reduced window-edge dock previews and initial pane sizing to a smaller sidebar/shelf estimate instead of a half-screen split.

Verified

• DENDER: floating tab can split a docked panel edge again.
• DENDER: floating tab can dock to the app/window edge.
• Photo Edit: floating tab can dock to the app/window edge at about 20% width.
