- tui.spec: exercise a goal-sourced injected context card (labels by
source kind, not plugin name), closing the last uncovered branch in
tui/src/index.ts that the CI coverage gate caught.
- time-context.e2e / goal.e2e: filter injected context by source now
that it is a user/message (plugin/goal source), and count goal
continuation rounds by round>0 rather than event type.
