Eliminates the two-chat experience on the overview page:
- CooChat now pre-loads Atlas conversation history on mount, showing
the full discovery conversation in the left panel. Atlas messages
render with a blue "A" avatar; COO messages use the dark "◈" icon.
A "Discovery · COO" divider separates historical from new messages.
- FreshIdeaMain detects when a PRD already exists and replaces the
duplicate AtlasChat with a clean completion view ("Discovery complete")
that links to the PRD and Build pages. Atlas chat only shows when
discovery is still in progress.
Made-with: Cursor
- New top navbar in ProjectShell: logo + project name | Build | Market |
Assist tabs | user avatar — replaces the left icon sidebar for project pages
- CooChat extracted to components/layout/coo-chat.tsx and moved into the
shell so it persists across Build/Market/Assist route changes
- Build page inner layout simplified: inner nav (200px) + file viewer,
no longer owns the chat column
- Layout: [top nav 48px] / [Assist chat 320px | content flex]
