feat: add ButtonGroup, theme toggle, dark theme fixes, remove shift references

- Add ButtonGroup primitive: multi-select toggle with colored dot indicators
- Replace FilterPill status filters with ButtonGroup in TopBar and EventFeed
- Add light/dark mode toggle to TopBar (moon/sun icon)
- Fix dark theme: add --purple/--purple-bg tokens, replace all hardcoded
  #F3EEFA/#7C3AED with tokens, fix --amber-light text contrast in sidebar,
  brighten --sidebar-text/--sidebar-muted tokens, use color-mix for
  ProcessorTimeline bar fills
- Remove all "shift" references (presets, labels, badges)
- Shrink SegmentedTabs height to match search bar and ButtonGroup
- Update COMPONENT_GUIDE.md with new components and updated descriptions
- Add ButtonGroup demo to Inventory
- Add README.md with setup instructions and navigation guide

+# Cameleer3 Design System
+
+A component library and interactive UI prototype for the Cameleer3 monitoring platform. This project contains both the reusable design system (primitives, composites, layout components) and a fully functional mock application demonstrating all pages and interactions.
+
+## Prerequisites
+
+- **Node.js** 20 or later (tested with 22.x) — [https://nodejs.org](https://nodejs.org)
+- **Git** — [https://git-scm.com](https://git-scm.com)
+
+No other tools, accounts, or access to external registries are required. All dependencies are published on the public npm registry.
+
+## Getting Started
+
+```bash
+# 1. Clone the repository
+git clone <repo-url> cameleer-design-system
+cd cameleer-design-system
+
+# 2. Install dependencies
+npm install
+
+# 3. Start the development server
+npm run dev
+```
+
+The dev server will start at **http://localhost:5173** (Vite will print the exact URL).
+
+## Available Scripts
+
+| Command | Description |
+|---------|-------------|
+| `npm run dev` | Start the development server with hot reload |
+| `npm run build` | Type-check and build the production bundle |
+| `npm run preview` | Serve the production build locally |
+| `npm test` | Run the test suite (Vitest, 332 tests) |
+| `npm run lint` | Run ESLint |
+
+## Navigating the Prototype
+
+Once the dev server is running, open **http://localhost:5173** in your browser. The application includes these sections:
+
+### Sidebar Navigation
+
+- **Applications** — Exchange monitoring dashboard
+  - `/apps` — All exchanges across all applications
+  - `/apps/:appId` — Filtered by application
+  - `/apps/:appId/:routeId` — Filtered by application and route
+  - Click the ↗ icon on any row to open the full **Exchange Detail** page
+
+- **Agents** — JVM agent health monitoring
+  - `/agents` — Overview of all agent instances grouped by application
+  - `/agents/:appId` — Single application's agents
+  - `/agents/:appId/:instanceId` — Instance detail with CPU, memory, threads, GC charts
+
+- **Routes** — Per-route performance metrics
+  - `/routes` — Aggregated KPI cards, route performance table, charts
+  - `/routes/:appId` — Filtered by application
+  - `/routes/:appId/:routeId` — Per-processor statistics and route flow diagram
+
+- **Admin** — User management (RBAC), OIDC configuration, audit log
+  - `/admin/rbac` — Users, groups, roles with inline editing
+  - `/admin/oidc` — OIDC provider configuration form
+  - `/admin/audit` — Searchable audit log table
+
+- **Inventory** — Component showcase
+  - `/inventory` — Interactive demos of every design system component
+
+### Top Bar Controls
+
+- **Search** (Ctrl+K) — Full-text search across applications, routes, agents, exchanges
+- **Status Filters** — Toggle OK / Warn / Error / Running to filter exchanges
+- **Time Range** — Preset time ranges (1h, 3h, 6h, Today, 24h, 7d) or custom date/time picker
+- **Theme Toggle** (☾/☀) — Switch between light and dark mode
+
+### Key Interactions
+
+- **Exchange slide-in panel** — Click any row in the exchanges table to open a detail panel on the right showing overview, errors, route flow, and processor timeline
+- **Exchange detail page** — Click the ↗ icon or "Open full details" link for the full inspector with Message IN/OUT panels and correlation chain
+- **Processor selection** — On the exchange detail page, click any processor in the timeline or flow diagram to see its message snapshots
+- **Starring** — Hover any item in the sidebar trees and click the star to pin it to the Starred section
+- **Dark mode** — Click the moon/sun icon in the top bar to toggle themes
+
+## Project Structure
+
+```
+src/
+  design-system/
+    primitives/     # Atomic components (Button, Input, Badge, StatusDot, ...)
+    composites/     # Composed components (DataTable, Modal, EventFeed, RouteFlow, ...)
+    layout/         # Page-level layout (AppShell, Sidebar, TopBar)
+    providers/      # React context providers (Theme, CommandPalette, GlobalFilter)
+    tokens.css      # Design tokens (colors, spacing, typography, shadows)
+    utils/          # Shared utilities (hashColor, timePresets)
+  pages/            # Application pages (Dashboard, Routes, AgentHealth, Admin, ...)
+  mocks/            # Static mock data (exchanges, routes, agents, metrics, sidebar)
+```
+
+## Tech Stack
+
+- **React 19** + **TypeScript**
+- **Vite** for development and bundling
+- **CSS Modules** for styling (all colors via design tokens)
+- **Vitest** + **React Testing Library** for tests
+- No runtime CSS-in-JS, no Tailwind, no external component libraries
+
+## Notes
+
+- All data is static mock data — no backend or API calls required
+- The prototype is fully self-contained and works offline after `npm install`
+- Light and dark themes are supported throughout
+- Fonts (DM Sans, JetBrains Mono) are loaded from Google Fonts and require an internet connection on first load
