Empty-state rethink: replace "Start a conversation." with a richer
landing showing recent conversations (top 5 as resume links) and a
voice-mode entry button. Gated to full variant only; widget/briefing
keep the simple message.
Context sidebar: switch from grid column (4-col layout) to absolute
overlay on the right gutter (3-col layout). The reading column is now
always symmetrically centered regardless of whether the sidebar is
visible — eliminates the leftward shift that occurred when context
notes appeared.
