feat(ui): extract shared Badge + Kbd primitives (U0.5)

[OBenner]

What

First U0.5 foundational primitives for the shared design system, de-duplicating the tonal-pill visual language that had drifted across three screens (each with its own __badge CSS).

• Badge (libs/ui/src/primitives) — tone (good/info/warn/bad/neutral, from the shared BadgeTone) + size (sm dense card chip / md detail badge). The tone colors were byte-identical across screens; size preserves the two historical sizings exactly.
• Kbd — inline keyboard-hint text.
• Refactored KanbanBoard (statusChip + outcome badges → <Badge size=sm>), TaskDetail (badges → <Badge size=md>), BoardToolbar (⌘K → <Kbd>); removed the now-duplicated .ac-kanban__badge / .ac-task-detail__badge / .ac-toolbar__kbd CSS.

Why this doesn't include Storybook

The repo has no Storybook, and CI installs frontend deps via npm ci against the hoisted root lockfile (workspaces) then typechecks/builds apps/frontend against it. A large Storybook dependency tree is exactly the lockfile/nesting change that has reddened all frontend CI before. So I'm landing the durable, zero-dep primitives here and staging Storybook + the Button/Input primitives as a separate U0.5b PR where the dependency's CI impact can be isolated and watched without blocking this.

Verification

Pixel-identical, confirmed live via computed styles: sm = min-height 22 / padding 0 7px / 10.5px·780 / radius 6 / nowrap; md = 2px 8px / 11px·600; both tones resolve to the same tokens (info = --blue/--blue-soft). libs/ui + Electron tsc 0, 24 adapter/filter tests green, zero stale badge/kbd classes remain.

Warning

Review limit reached

@OBenner, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 50 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Adds shared Badge and Kbd UI primitives, exports them from the UI package, and replaces screen-local badge and keyboard-hint markup and styling in KanbanBoard, TaskDetail, and BoardToolbar.

Changes

Shared UI primitives

Layer / File(s)	Summary
Primitive contracts and styling libs/ui/src/primitives/*, libs/ui/src/index.ts	Adds Badge and Kbd components, their CSS, prop types, and top-level exports.
Keyboard hint integration libs/ui/src/screens/BoardToolbar.*	Renders the search shortcut with Kbd and removes the local keyboard-hint rule.
Badge rendering integration libs/ui/src/screens/KanbanBoard.*, libs/ui/src/screens/TaskDetail.*	Renders status and task badges with Badge, mapping tone and size values while removing local badge styles.
