Goal

Enrich kanban cards with PR status, CI status, token count, and graduated attention level to make the kanban view more operationally useful.

Scope

• In: Card content enrichment (PR link/status, CI badge, token count, attention level indicator), visual density improvements
• Out: Swim lanes by repo (separate issue), drag-to-prioritize (deferred)

Acceptance Criteria

• Kanban cards show PR status (open/merged/draft) with icon when available
• Kanban cards show token count (formatted via FormatTokenCount)
• Kanban cards show graduated attention level color/icon
• Cards remain readable at typical terminal widths (80-120 cols)
• No regression in kanban navigation or interaction
• Unit tests for card rendering logic

Dependencies

• Parent: UI Rework: Make agent-viz more helpful and better looking #192
• Depends on: graduated attention levels sub-issue

Validation

Run go test ./internal/tui/components/kanban/.... Visual inspection at various terminal widths.
