* feat(web): surface PR mergeability + conflict state in the CI popover
The CI hover popover showed checks/reviews but nothing about mergeability, so an
unmergeable PR silently dropped its merge button with no reason. Add a mergeability
row that reuses the detail panel's conflict banner + "Resolve conflicts" agent prompt
for dirty PRs, a "Behind base" chip, and a branch-protection note explaining why a
blocked PR is gated. Replace the compact merge split-button+dropdown with an inline
primary + "or <method>" buttons so the menu's detached portal no longer closes the
hover popover.
* feat(web): reflect PR mergeability in status colors and badges
The PR status pill, badge, and chat-input CI chip derived their colour from
checks/reviews only, so a conflicted or blocked PR still read as a green "all good"
check. Map dirty -> red, behind -> amber, and branch-protection blocked -> amber across
getPRStatusColor, the PRStatusIcon badge, and the chip glyph, so the indicators agree
with the popover. Blocked stays sky/in-progress while a requested review is still
outstanding (that's the awaiting-review gate, not a hard block).
* refactor(web): remove dead merge-menu keep-open plumbing
The compact merge control was redesigned to inline buttons (no dropdown portal),
which already fixes the hover popover closing. That leaves the keepOpen ref /
setKeepOpen / onMergeMenuOpenChange / onMenuOpenChange chain threaded through
usePopoverInteractions, PRCIPopover, and PRMergeButton unreachable: the popover
always renders PRMergeButton with compact, and the only DropdownMenu lives in the
non-compact detail-panel path that never passes the callback. Drop the unused
scaffolding (flagged by OpenCode + greptile).
* fix(web): keep CI popover quiet for blocked PRs only awaiting review
PRMergeabilityRow rendered "Blocked by branch protection" for any blocked PR,
including one blocked solely because a requested reviewer hasn't responded. That
contradicted the chip/pill/badge, which deliberately read that case as the calm
"awaiting review" state. Skip the note (render nothing) when isPRAwaitingReview is
true, and narrow blockedReason so an empty checks_state no longer falsely claims a
required status check failed. Flagged by Claude (blocker) and greptile.
* refactor(web): rename mergeability-notice compact prop to popover
The `compact` prop made the chip/text larger (to match the popover's text-xs rows)
while ConflictBanner's `compact` tightened padding — so "compact" rendered bigger,
which reads as inverted. Rename it to `popover` (the variant rendered inside the CI
hover popover) and document that the chip intentionally matches the popover rows.
No visual change. Flagged by cubic.
* fix(web): show default cursor on disabled compact merge alternates
The compact "or <method>" alternates kept cursor-pointer while disabled (during the
~1s merging state); add disabled:cursor-default to match the primary button. Flagged
by OpenCode.
