feat(web): refresh pull request details

[maria-rcks]

What changed

• Refreshes Pull Request list and detail geometry, filters, sticky metadata, branch actions, stacked-base state, and loading skeletons.
• Keeps expanded detail spacious while using a compact header only after scroll.
• Makes repository, PR, branch-copy, checkout, conflict, reviewer, label, and timeline controls consistent at narrow and wide widths.

Screenshots

Before	After

## Why

This is a large visual review on its own. Separating it keeps workspace primitives below and terminal, composer, and tool-call behavior out of the diff.

Validation

• Pull Request filter and detail logic tests
• Pull Request link tests
• Affected-package typechecks
• Changed-file lint and formatting checks

Note

Medium Risk
Large UI refactor across PR detail, list, and VCS/ref parsing; conflict action ordering and new stacked-PR heuristics affect merge/checkout flows, though logic is covered by added tests.

Overview
Pull request detail and list get a visual and interaction pass: shared WorkspacePageHeader / WorkspacePageContainer, filter and refresh controls aligned with other workspace pages, and the right-panel toggle only when a PR is selected (with a clearer unavailable tooltip).

PullRequestDetailPanel drops the chromeVariant prop and always collapses header metadata on scroll, with tighter top chrome and segmented tab toggles. Resolve conflicts becomes the primary header action when merge conflicts exist (ahead of draft-ready / merge). The repository name can open the repo root via new changeRequestRepositoryUrl. Stacked PRs are inferred from local VCS refs (isStackedPullRequestBase) and shown with a layers icon on the base branch. Loading uses a full-panel PullRequestDetailGhost instead of per-tab ghosts inside the scroll area.

PanelLayoutControls wraps disabled toggles so tooltips still work on unavailable terminal/right-panel buttons. pullRequestHandoffLabels no longer exposes resolve/conflicts strings (conflicts are handled in the header). Summary meta rows use a fixed label column grid.

Note

Refresh pull request detail panel with conflict resolution, stacked PR indicators, and usage page redesign

• Overhauls PullRequestDetailPanel: chrome always collapses on scroll, conflict resolution is promoted to a primary destructive button, tab nav switches to a segmented ToggleGroup, and the repository label becomes a clickable external link.
• Adds isStackedPullRequestBase helper and a VCS refs query to detect stacked PRs, showing a LayersIcon indicator in the header when the base branch is not the repo default.
• Redesigns the Usage page with responsive breadcrumb controls (segmented toggles on desktop, selects on mobile), fixed provider order with session counts, and a simplified Totals section without detail subtext.
• Adds per-provider sessions tracking to mergeUsage so providers with sessions but zero spend appear in the provider list.
• Adds changeRequestRepositoryUrl to derive a repository root URL from a PR URL across GitHub, GitLab, Bitbucket, and Azure DevOps.
• PanelLayoutControls tooltips stay accessible when toggles are disabled; the right-panel toggle on the pull requests route requires an active PR selection.
• Behavioral Change: pullRequestHandoffLabels no longer returns resolve or resolveConflicts keys; callers that depended on those entries will receive only fix-related labels.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces new features including stacked pull request detection (with LayersIcon indicators), clickable repository links that open externally, and changes the priority logic for action buttons. The scope of new user-facing behavior and UI restructuring warrants human review.

No code changes detected at eee6a04. Prior analysis still applies.

Reviewed the pull-request chrome rework against the shared primitive/Tailwind ownership rules. The primitive migrations look sound (SegmentedTab* for the tabs, Button behind MenuTrigger render in the filters menu with --control-icon-color carrying the pressed tone, WorkspacePageHeader/WorkspacePageContainer keeping drag-region, WCO inset and the collapsed-sidebar titlebar inset, ps-[8.5px] matching the existing leading-icon button call sites). Two layout regressions introduced by changed lines are noted inline.

One new finding on the conflict primary action. The two findings from the previous run (tab-nav padding vs. scroll compensation, and MetaRow losing its vertical padding) are still open on the current head and are not repeated here.

One finding on the reworked pull request detail header. Details inline.

^{Posted via Macroscope — UI Consistency}

[macroscopeapp]

One consistency issue found in the reworked pull request chrome. Everything previously raised (segmented track classes now live in the ToggleGroup primitive, the disabled-toggle tooltip wrappers, the copy-branch focus ring, the xs icon sizing, MetaRow padding, action-row DOM order, and the restored collapse rationale comments) is addressed at this head.

^{Posted via Macroscope — UI Consistency}

[macroscopeapp]

One consistency finding in this revision. Everything else in the restructure lines up with the shared primitives: the segmented tab group now takes its track from the segmented variant, the filters trigger renders through Button, the panel header goes through WorkspacePageHeader/WorkspacePageContainer, both disabled panel toggles hang their tooltip on a wrapper (matching ConnectionsSettings), and the detail ghost mirrors the new chrome and MetaRow grid.

[macroscopeapp]

One finding: the new stacked-base indicator has no user-facing explanation. Everything else in this pass looks consistent with the shared primitives — the tooltip triggers on the disabled panel toggles are now wrapped uniformly, the segmented track lives in ToggleGroup rather than the call site, the filter/refresh controls go through Button, and the header/container geometry comes from WorkspacePageHeader/WorkspacePageContainer.

[macroscopeapp]

One finding on the rebuilt detail-panel chrome: the top row's crossfading layers lost their sm:text-xs step. Everything else checked out — the panel-layout tooltip triggers, the filters trigger migration to Button, the segmented tab group, and the MetaRow/ghost geometry all line up with the shared primitives.
