fix(app): simplify titlebar worktree badge

[Astro-Han]

Summary

• Show only the worktree name in the titlebar worktree badge.
• Move branch and directory details into a structured three-row hover tooltip.
• Keep the badge compact with a higher 280px cap and add focused regression coverage.

Why

The titlebar previously combined worktree name and branch in one badge, which repeated information and caused long names to truncate too early. The badge now keeps the titlebar scannable while the tooltip carries the full context.

Related Issue

No linked issue. Reported from local product review.

Human Review Status

Pending. A human should make the final merge decision after reviewing the final diff and verification evidence.

Review Focus

• Whether the tooltip information order, Worktree / Branch / Location, matches the intended titlebar hierarchy.
• Whether 280px is the right cap now that the visible badge only shows the worktree name.

Risk Notes

Low. This is a small titlebar UI change with no data, permissions, desktop shell, packaging, updater, signing, or migration impact.

How To Verify

Focused tests: 2 passed, 0 failed for pawwork-worktree-badge.test.tsx
Typecheck: tsgo -b completed successfully in packages/app
Final diff review: only worktree badge component and its focused test changed

Screenshots or Recordings

Not captured in this session. Visible change is covered by focused component tests; manual UI review is still recommended before merge.

Summary by CodeRabbit

• New Features

  • Worktree badge now includes a tooltip showing structured rows: Worktree, Branch, Location (with fallbacks).

• Improvements

  • Badge label selection now prefers the worktree name, then branch/directory, for clearer identification.
  • Button styling tightened for a more compact display and improved tooltip placement/visibility.

• Tests

  • Updated tests confirm compact label rendering and verify tooltip structure, content, and placement.

📝 Walkthrough

Walkthrough

PawworkWorktreeBadge replaces title-attribute hover text with a Tooltip wrapper, adds a WorktreeTooltipRow helper, chooses label via name || branch || directory || "Worktree", updates button max-width styling, and updates tests to mock Tooltip and assert the structured tooltip and visible label.

Changes

Worktree Badge Tooltip Upgrade

Layer / File(s)	Summary
Data / Helper packages/app/src/pages/layout/pawwork-worktree-badge.tsx	Adds WorktreeTooltipRow helper that renders a labeled row and defaults missing values to "Not available"; supports emphasis styling for the Worktree row.
Core Implementation packages/app/src/pages/layout/pawwork-worktree-badge.tsx	Replaces title-based label with label() selection (`name
Wiring / Presentation packages/app/src/pages/layout/pawwork-worktree-badge.tsx	Wraps Button with Tooltip (uses placement="bottom"), removes title prop from the button, and updates button classes to include the new max-w constraint for compact label rendering.
Tests / Mocking packages/app/src/pages/layout/pawwork-worktree-badge.test.tsx	Adds mock for @opencode-ai/ui/tooltip exposing Tooltip and TooltipKeybind stubs. Updates tests to assert visible span text is only the worktree name, button.props.title is undefined, button classes include max-w-[280px], tooltip placement === "bottom", tooltip class/styling, and that tooltip.props.value is a div with data-component="pawwork-worktree-tooltip" containing ordered rows: Worktree, Branch, Location. Adds a test for empty name fallback showing Not available without duplication.

Poem

🐰 A badge that once hid text inside a title,
Now pops a panel tidy and gentle;
Worktree, Branch, Location in a neat little file,
No duplicate fallbacks, no accidental recital,
I hop and I nudge — the tooltip's quite genteel!

Code Review

This pull request replaces the native title attribute on the PawworkWorktreeBadge with a custom Tooltip component, providing a structured view of worktree details like name, branch, and location. It also increases the badge's maximum width and updates the test suite. Feedback suggests using the direct worktree name in the tooltip to avoid redundancy and adding layout classes to the tooltip trigger to ensure proper shrinking in the titlebar.
