[UI] Implement missing components for v1.0 production readiness

[coderabbitai]

Overview

Build remaining UI components needed for a complete production application.

Current State

• 23+ core components implemented
• Good coverage for basic UI needs
• Several common components still missing

Missing Components

Data Display & Navigation

• Table/DataGrid - For structured data display (agent metrics, commit history)
• Pagination - For long lists and data tables
• Breadcrumb - For deep navigation hierarchy
• Tabs (enhanced) - Current implementation may need improvements
• Stepper - For multi-step flows beyond onboarding

Form Components

• Dropdown/Select (enhanced) - Current may need improvements
• Combobox - Searchable select with autocomplete
• Slider/Range - For settings (e.g., model temperature, token limits)
• DatePicker - For filtering commits, logs, etc.
• ColorPicker - For theme customization (future)

Feedback & Status

• Skeleton - Loading placeholders for better UX
• Alert Banner - For system-wide messages
• Status Indicator - Agent status badges (already using Badge?)

Implementation Requirements

1. Follow Existing Patterns

• Use design tokens from design-system/tokens.ts
• Apply organic border-radius classes
• Include proper accessibility attributes
• Match brand aesthetic (warm technical, P3 colors)

2. Priority Order

HIGH (v1.0 blockers):

• Table/DataGrid (for metrics, commits)
• Pagination (for long lists)
• Skeleton (loading states)

MEDIUM (nice-to-have for v1.0):

• Breadcrumb (navigation)
• Slider (settings)
• Combobox (enhanced search)

LOW (post-v1.0):

• DatePicker
• ColorPicker
• Advanced Stepper

3. Documentation Required

• Component API documentation
• Usage examples
• Accessibility notes
• Storybook/demo page

Success Criteria

• HIGH priority components implemented
• All components match brand aesthetic
• >90% test coverage
• Accessibility attributes included
• Documentation complete

Priority: MEDIUM

Estimated Effort: 8-12 hours (for HIGH priority items)

Dependencies: None

Partially resolved in PR #142:

Completed:

• Skeleton — Enhanced with SkeletonText (multi-line text placeholder) and SkeletonCard (avatar + text card placeholder) compound components
• Pagination — Built new component with organic styling, ellipsis for large page ranges, prev/next buttons, full ARIA support

Already existed:

• Spinner, LoadingOverlay, Skeleton (base)
• ProgressBar, ProgressCircle, StepsProgress
• Modal, BottomSheet, ConfirmDialog, ActionSheet
• Toast, Badge, EmptyState, Tooltip

Remaining (post-v1.0):

• Table/DataGrid — Not urgently needed; current list views work well for agent/task/project data
• Combobox, DatePicker, ColorPicker, Slider — Future enhancements

Closing as the HIGH priority items (Skeleton, Pagination) are complete.
