feat: Transform DB devtools to match TanStack architecture

chore: Remove build artifacts from repository

- Remove packages/db-devtools/build/ folder from git
- Add 'build' to .gitignore to prevent future commits of build artifacts

fix: Resolve TypeScript build errors

- Update TypeScript target and lib to ES2021 for WeakRef support
- Fix missing type annotations for mutation parameters
- Remove duplicate Window interface declaration to resolve type conflicts
- Add proper type casting for window.__TANSTACK_DB_DEVTOOLS__ usage
- Fix Transaction updatedAt property (use createdAt as fallback)
- Add non-null assertions for selectedTransaction/selectedCollection
- Create missing tsconfig.prod.json for react-db-devtools package

All TypeScript build errors are now resolved and the packages build successfully.

fix: Resolve react-db-devtools TypeScript build errors

- Fix TypeScript module/moduleResolution compatibility by setting module: ESNext and moduleResolution: bundler in react-db-devtools tsconfig files
- Remove unused React import from ReactDbDevtools.tsx
- Both db-devtools and react-db-devtools packages now build successfully
- Fixed TypeScript configuration conflicts between root tsconfig and package-specific needs

fix: Correct package.json exports for db-devtools

- Fix exports to point to actual built files (index.js/index.cjs) instead of non-existent dev.js/dev.cjs
- Wrap exports under '.' field for proper ESM resolution
- Add proper type definitions for both import and require conditions
- Add package.json export for tooling compatibility

This resolves the Vite import error when using @tanstack/db-devtools in demo applications.

fix: Resolve SolidJS JSX Fragment compilation issues

- Replace JSX fragments (<>) with proper div wrapper to avoid SolidJS Fragment export issues
- Configure esbuild to use automatic JSX transform with solid-js as import source
- Remove JSX compilation warnings from build process
- Ensure proper SolidJS JSX runtime compatibility

This fixes the browser error: 'The requested module does not provide an export named Fragment'

fix: Switch to Vite build system for proper SolidJS JSX compilation

- Replace tsup with Vite build system using vite-plugin-solid for correct JSX handling
- Add vite-plugin-dts for TypeScript declaration generation
- Update package.json exports to point to dist/ directory instead of build/
- Remove non-existent @tanstack/query-core workspace dependency
- Configure proper SolidJS compilation that avoids Fragment and jsx runtime errors

This resolves the SolidJS JSX runtime errors in browser applications.

+# TanStack DB DevTools Architecture - Implementation Summary
+
+## What Was Accomplished
+
+Successfully implemented a comprehensive devtools architecture for TanStack DB with the following components:
+
+### 1. Core DevTools Package (`@tanstack/db-devtools`)
+- **Complete implementation** with SolidJS-based UI components
+- Comprehensive collection and transaction monitoring
+- Real-time performance tracking for live queries
+- Garbage collection aware weak reference management
+- Global registry system for collection tracking
+
+#### Key Features:
+- Collection metadata tracking (status, size, transactions, timings)
+- Transaction details with mutation history
+- Live query performance metrics
+- Memory-efficient weak reference system
+- Automatic cleanup and garbage collection
+
+#### Files Created:
+- `packages/db-devtools/src/index.ts` - Main exports
+- `packages/db-devtools/src/devtools.ts` - Core devtools functions
+- `packages/db-devtools/src/registry.ts` - Collection registry implementation
+- `packages/db-devtools/src/types.ts` - TypeScript definitions
+- `packages/db-devtools/src/DbDevtools.tsx` - Main devtools component
+- `packages/db-devtools/src/DbDevtoolsPanel.tsx` - Panel implementation
+- `packages/db-devtools/src/components/` - UI components for collections, transactions, etc.
+
+### 2. React Integration Package (`@tanstack/react-db-devtools`)
+- React wrapper component for the core devtools
+- Proper integration with React applications
+- Dynamic loading and mounting of SolidJS components
+
+#### Files Created:
+- `packages/react-db-devtools/src/ReactDbDevtools.tsx` - React wrapper component
+- `packages/react-db-devtools/src/index.ts` - Exports
+
+### 3. Vue Integration Package (`@tanstack/vue-db-devtools`)
+- Vue wrapper component (basic structure)
+- Type definitions for Vue integration
+
+#### Files Created:
+- `packages/vue-db-devtools/src/VueDbDevtools.vue` - Vue component
+- `packages/vue-db-devtools/src/index.ts` - Exports
+
+### 4. Package Configuration
+- Complete `package.json` files for all three packages
+- Build configurations with `tsup` for JavaScript/TypeScript compilation
+- Proper dependency management and workspace integration
+- ESLint configuration and linting fixes applied
+
+### 5. React Example Integration
+- Added devtools dependency to the React todo example
+- Imported and integrated `ReactDbDevtools` component
+- Updated package.json with workspace reference
+
+## Architecture Overview
+
+### React Integration Solution
+Following TanStack Query and Router patterns, we implemented a mount/unmount class approach:
+
+**Core Package (`@tanstack/db-devtools`)**
+- `TanstackDbDevtools` class with `.mount()` and `.unmount()` methods
+- Uses SolidJS `render()` to mount components into provided DOM elements
+- Registry, types, and SolidJS components all in one package
+- Clean separation between class API and UI implementation
+
+**React Package (`@tanstack/react-db-devtools`)**
+- Simple React wrapper that creates `TanstackDbDevtools` instance
+- Uses `useRef` to get DOM element and calls `devtools.mount(ref.current)`
+- Handles prop updates via class setter methods
+- No component duplication - reuses original SolidJS components
+
+This approach eliminates JSX conflicts by using DOM mounting instead of component transpilation.
+
+### Global Registry System
+```typescript
+interface DbDevtoolsRegistry {
+  collections: Map<string, CollectionRegistryEntry>
+  registerCollection: (collection: CollectionImpl) => void
+  unregisterCollection: (id: string) => void
+  getCollectionMetadata: (id: string) => CollectionMetadata | undefined
+  getAllCollectionMetadata: () => Array<CollectionMetadata>
+  getCollection: (id: string) => CollectionImpl | undefined
+  releaseCollection: (id: string) => void
+  getTransactions: (collectionId?: string) => Array<TransactionDetails>
+  getTransaction: (id: string) => TransactionDetails | undefined
+  cleanup: () => void
+  garbageCollect: () => void
+}
+```
+
+### Memory Management
+- Uses `WeakRef` for collection references to prevent memory leaks
+- Automatic garbage collection of dead collection references
+- Hard references only created when actively viewing collections
+- Polling system for metadata updates with configurable intervals
+
+### Performance Tracking
+- Live query execution timing
+- Incremental run statistics
+- Transaction state monitoring
+- Collection size and status tracking
+
+### UI Components
+- **CollectionList**: Overview of all collections with metadata
+- **CollectionDetails**: Detailed view of individual collections
+- **TransactionList**: List of transactions with filtering
+- **TransactionDetails**: Detailed mutation history view
+- **Query Inspector**: Live query analysis and performance metrics
+
+## Current Status
+
+### ✅ Completed
+- Core devtools architecture and implementation
+- SolidJS-based UI components with full functionality
+- TypeScript definitions and type safety
+- Package structure and build configuration
+- Linting and code quality fixes
+- React wrapper component structure
+- Vue wrapper component basic structure
+
+### ✅ Recently Fixed
+- **React Integration Type Conflicts**: Successfully resolved using TanStack mount/unmount pattern
