- Widget is now a bottom-anchored dock spanning the content width
(max-width 1200px, rounded top corners, bg-secondary, upward shadow)
instead of a floating corner box.
- Drop the closed state and ✕ button — widget is always present,
matching KnowledgeView's pattern. Collapsed = input-only dock,
expanded = full ChatPanel above the input.
- Grid ratio 1fr:2fr → 0.85fr:2.15fr so tasks get a touch less room
and notes a touch more.
- Workspace note-rail (the notes picker column inside the editor)
widens from 155px to 200px so note titles breathe.
