Add Expo mobile app with multi-tenant support (#97)

## Summary
Introduces a new Expo-based React Native mobile application
(`apps/mobile`) as a tenant-branded, multi-tenant mobile client. Also
establishes a shared package (`packages/shared`) for logic reuse between
web and mobile.

## Key Changes

- **New mobile app** (`apps/mobile/`)
  - Expo SDK 55 with Expo Router for file-based routing
  - TypeScript strict mode with matching tsconfig to web
  - NativeWind for Tailwind CSS styling in React Native
  - Supabase client integration with AsyncStorage for persistent auth
  - TanStack Query v5 for data fetching
  - React Hook Form + Zod for form validation
  - Grouped layouts: `(auth)/` and `(app)/` to mirror web structure
  - EAS Build/Submit configuration for iOS and Android deployment
  - Environment variables using `EXPO_PUBLIC_` prefix

- **New shared package** (`packages/shared/`)
- Placeholder for extracting shared validation schemas, constants, and
types
  - Used by both web and mobile applications
  - Strict TypeScript configuration

- **Documentation updates** (`CLAUDE.md`)
  - Added mobile stack details (framework, styling, auth, deployment)
  - Updated project structure to include mobile and shared packages
  - Added mobile-specific commands and conventions
- Clarified that mobile uses client-side Supabase with RLS as security
boundary

## Implementation Details

- Mobile auth persists via AsyncStorage with auto-refresh enabled
- All Supabase calls go through the client SDK directly (no server
components/actions)
- RLS policies enforce security on the database layer
- Shared business logic will be centralized in `@cowork/shared` to avoid
duplication
- Mobile env vars follow Expo conventions (`EXPO_PUBLIC_` prefix)
- Babel configured with NativeWind JSX transform for Tailwind support

 - Database types auto-generated. Never hand-edit `database.ts`.
 - Small files (~200 lines max). One component per file.
 - Colocate related files: page, components, actions, hooks in the same directory.
+- Mobile screens use Expo Router file conventions. Group layouts in `(auth)/` and `(app)/` match web.
+- All Supabase calls in mobile go through the client SDK directly — no server components, no server actions. RLS is the security boundary.
+- Shared business logic (validation, calculations, constants) lives in `@cowork/shared`, imported by both web and mobile.
+- Mobile env vars use `EXPO_PUBLIC_` prefix (equivalent to `NEXT_PUBLIC_` on web).
