* feat(web): tabbed multi-PR CI popover for topbar button and chat status chip
* test(e2e): cover multi-PR CI popover tabs, chip aggregate, and dropdown
* fix(web): address multi-PR popover review feedback
- suppress hover popover while the PR dropdown is open (no stacked overlays)
- repo-scope tab testids so same-number PRs on different repos stay unique
- guard non-array taskPRs store value in PRStatusChip (same as PRTaskIcon)
- add tablist/tab/aria-selected semantics to the popover tabs
* fix(web): warm default PR only, skip terminal PRs, add tabpanel ARIA
- chip background-sync warms pickDefaultPR (the tab the popover opens), not list head
- PRFeedbackWarmer skips merged/closed PRs (no wasted fetches in topbar path)
- tabpanel role + aria-controls/labelledby wire tabs to the panel
* fix(web): complete ARIA tabs keyboard model in multi-PR popover
- roving tabindex: only the active tab in the page tab order
- ArrowLeft/ArrowRight move selection + focus within the tablist (wrapping)
- stable useId-scoped tabpanel id so every tab's aria-controls resolves
- document topbar-only scoping of prCheckGroup e2e helpers
* refactor(web): skip duplicate rank call for first PR in pickDefaultPR
