Change

Three changes to the chat composer, in one PR:

• The control row is v0.4.8's again. feat(chat): port t3code chat rendering, composer and settings features #951 rearranged the card's last row after t3code: the model group came first as plain text with hairlines, and add / mic / task chip moved next to Send. This PR puts back the released layout: add, the mic and the task chip on the left, and the filled model pill (Opus 5.5 · High) next to the round Send/Stop button. The CSS for that row, the DOM order and the middle dot are v0.4.8's. The message box and attachment insets stay main's: v0.4.8's wider inset wrapped the prompt placeholder onto a third line at 390x500 / 24px, and the prompt card lost the room prompt-dock-demo-regression checks. The things added since then stay: the Compact button, the notices and the strip.
• A worktree's strip names its repository. herdr names a worktree's checkout folder after the branch with / turned into -, so in a linked worktree the strip said the same thing twice (worktree-lucky-forest-f1c8 … worktree/lucky-forest-f1c8). The folder's place now shows the repository (workspace.worktree.repo_name), still with the Worktree mark, and the title still holds the full path. Other workspaces keep showing the folder name.
• Settings → Chat → Composer → "Folder and branch" turns the strip off. It is on by default, scoped to this device and not included in telemetry. Strings are translated in ko/ja/zh/tr.

The unreleased changelog line from #951 that described the t3code row now covers only the strip. A new fragment covers the repository name and the setting.

Validation

• bun run typecheck, build and generated types: ok.
• bun run test:unit: 3471 pass, 1 fail. The failure is server/voice.test.ts, the same one feat(composer): name the branch and mark a worktree in the strip under the message box #991 reported failing on main on this Mac. This PR touches nothing in server/ or shared/.
• New unit tests: composerStrip with repo, worktreeRepoName, and showComposerStrip sanitizing.
• scripts/composer-fit-demo-regression.ts: exit 0. Screenshots of the demo at 1280px and 390px show the same row as v0.4.8 (compared side by side).
• scripts/prompt-dock-demo-regression.ts: exit 0 after the rebase onto fix(composer): never cut an attached file's path #872 (it failed in CI run 38532789259 from the inset above).
• scripts/ui-regression.ts: the row-order assertion is restored to the v0.4.8 version. It was not run locally because it needs a live herdr test session.

📝 Summary

Summary by CodeRabbit

• New Features
  • The composer now shows the working folder and branch beneath the message box. For linked worktrees, it shows the repository name instead of the checkout folder.
  • You can hide this information with the Folder and branch setting under Settings → Chat → Composer.
• Improvements
  • Composer controls now sit on the left, with status information and the Send/Stop button on the right. Model details appear in a filled pill, and the context indicator remains visible.
  • In compact layouts, reconnecting or uploading status appears on its own row.

The composer control order and status presentation are updated. Linked worktrees display their repository name in the composer strip. A new Composer setting controls whether the strip appears.

Changes: Composer layout

Layer / File(s)	Summary
Composer controls and status presentation src/components/Composer.tsx, src/components/Composer.css, DESIGN.md, src/lib/composerLabelFit.ts, scripts/ui-regression.ts, scripts/composer-fit-demo-regression.ts	Attachment, dictation, and background-task controls appear before status; Send/Stop remains on the right. Status alignment, model pill styling, and responsive spacing are updated. Regression checks cover the revised control order and narrower viewports.

Composer folder and branch strip

Layer / File(s)	Summary
Linked-worktree repository naming src/lib/composerStrip.ts, src/lib/composerStrip.test.ts, src/components/Composer.tsx, src/components/PaneTerminal.tsx, src/App.tsx, src/AGENTS.md	The repository name from a linked worktree is passed to the composer strip and used as its folder label. The strip retains the full path.
Composer strip setting src/lib/settings.ts, src/components/SettingsDialog.tsx, src/lib/settings.test.ts, src/lib/i18n.*.ts, changelog.d/*	A Folder and branch setting controls the strip. It defaults to enabled, is device-scoped, and accepts boolean persisted values. Translations and changelog entries are added.

Assert that the compact status row stays above the controls.

The pending-upload cases at 320px and 330px check visibility and overlap, but not vertical ordering. A layout change could move the status below the controls while these checks still pass. Add a bounding-box assertion for the documented ordering.

Suggested fix

   return {
     draw: status.getAttribute("data-model") ?? "full", hintAlone: status.hasAttribute("data-hint-alone"),
     card: { width: surface.width, height: surface.height }, status: status.getBoundingClientRect().height,
