fix(web): thread details card gives titles room to read

[t3dotgg]

The thread details card got too crowded. Lineage rows showed both a timer and the word "Running", and PR rows put the number, checks, a chevron, and an action next to the title. On a 280px card, titles were cut to a few characters.

Now the title gets the space:

• Lineage: each row shows one item on the right. An agent shows only a short time ("45s", "1m", "1.5h", "14h"). The icon dot and the "N running" header already show the status. Forks, parents, queued and failed rows still show a status word, and "Failed" is red. The hover card keeps the exact time.
• PR row: when the PR has checks, an action, or a watch, the row splits into two lines. Line 1 is the full-width title. Line 2 has #number, checks ("2 failed" or "1/3", no chevron), the watch eye, and the action (Resolve, Ready, Fix or Merge). The second line sits tight under its own title, with a gap before the next PR, so stacked PRs read as pairs. PRs with nothing to show stay on one line.

Before	After

Watched PR: the eye sits on line 2 after the number and checks. Clicking it stops the watch.

The screenshots come from a local dev server with real data: four running delegated subagents, and a thread linked to two open PRs that have conflicts.

Web and desktop only. Mobile has its own agents sheet and does not change.

Walkthrough

The changes add compact elapsed-time formatting for agent rows, revise pull request detail row layouts and controls, and display failure counts in the pull request checks trigger.

Changes

Agent elapsed-time display

Layer / File(s)	Summary
Compact elapsed-time formatting apps/web/src/components/chat/AgentElapsed.tsx, apps/web/src/components/chat/AgentElapsed.test.ts	Adds an optional compact format that displays seconds, whole minutes, or tenths of an hour. Tests cover values from 45 seconds to 14 hours.
Agent relationship row display apps/web/src/components/chat/ThreadRelationshipsControl.tsx, apps/web/src/components/chat/ThreadRelationshipsControl.agents.test.tsx	Agent rows show compact elapsed time when available and the status is not failed or errored. Other eligible rows show a status label, with failed and errored labels styled as destructive.

Pull request details

Pull request detail row layout apps/web/src/components/chat/ThreadDetailsPrRow.tsx, apps/web/src/components/chat/ThreadDetailsControl.tsx, apps/web/src/components/chat/threadDetailsPanelStyles.ts	Moves the pull request title to its own line and places eligible checks, the watch control, and an action on the second line. Adds meta-action styling and a primary tone.
Pull request check-count trigger apps/web/src/components/pullRequest/PullRequestChecksPopover.tsx	Displays the number of failed or cancelled checks when the running-count display does not apply. Removes the chevron from the count variant.
