* fix(app): keep check rows the same height with and without "Add to chat"
A check row was minHeight 32 plus 8pt of vertical padding, but the xs
Button in its trailing slot is 28pt tall. The button stacked on the
padding rather than fitting inside the row, so a row grew to 44pt the
moment "Add to chat" appeared and the list visibly shifted as rows
gained the button.
Rows are single-line by construction, so the row now declares a fixed
height instead of a floor a child can outgrow. That height comes from
CONTROL_HEIGHTS, the same source the button sizes from, so the two
cannot drift apart later. GitLab pipeline rows share this style and get
the fix too.
* feat(app): summarize pull request checks and group them by status
The checks section listed every check inline under a bare "Checks"
header with three count pills. On a repo with a real matrix that meant
a wall of undifferentiated rows that pushed the activity timeline off
the pane, and the pills made the reader add up numbers to work out
whether the run was actually in trouble.
The section now leads with the answer — a headline that names the
outcome, a one-line count breakdown, and a ring showing the statuses in
proportion — then groups the rows by status with failures first, and
scrolls in place past roughly eight rows instead of growing without
bound. Groups collapse individually.
The derivation lives in checks-summary.ts as one pure function, so the
headline, the ring, and the group labels cannot disagree about the same
run. The rendering, the row, and the check identity move out of pane.tsx
into an owned module; the pane now wires it and nothing more.
Running checks also gain a timing. formatCheckRunDuration required both
a start and a completion, so anything still going showed nothing at all.
It now measures an unfinished run to now. The wire deliberately carries
formatted strings rather than raw timestamps — there is a test asserting
check timestamps are stripped — so the daemon does the measuring and the
client only decides how to say it: a bare "2m" on a running row would
read as "took 2m", so those rows say "running 2m".
