BREAKING CHANGE: Renamed system-analysis-server to deployment-orchestrator

This commit establishes a fully type-safe, provider-agnostic architecture
for deploying backend providers (Appwrite, Supabase, Firebase).

## Major Changes

### Architecture
- Renamed system-analysis-server → deployment-orchestrator
- Implemented factory pattern for compose generation
- Created discriminated union types for provider-specific configs
- Added type guards for safe type narrowing

### Provider System

- BaseComposeGenerator: Abstract class with common functionality
- AppwriteComposeGenerator: Full Appwrite support
- SupabaseComposeGenerator: Full Supabase support
- FirebaseComposeGenerator: Full Firebase support
- ComposeGeneratorFactory: Auto-registers all providers

### Type Safety
- Created provider-configs.ts with discriminated unions
- Type guards: isAppwriteConfig, isSupabaseConfig, isFirebaseConfig
- Validation functions with runtime + compile-time safety
- Zero type errors, strict TypeScript mode

### Testing Infrastructure
- Added TESTING_STRATEGY.md documentation
- npm run typecheck: Type checking without build
- npm run validate: Full validation pipeline
- Defined unit, integration, and E2E test patterns

## Benefits
- ✅ All 3 providers supported (was 1)
- ✅ Type-safe at compile time (was runtime errors)
- ✅ Extensible factory pattern (was hardcoded)
- ✅ Minimal code duplication (shared base class)
- ✅ Clear error messages (provider-specific)
- ✅ Testing strategy documented

## Technical Details
- Uses TypeScript discriminated unions for type safety
- Type guards enable safe type narrowing
- Factory pattern allows easy addition of new providers
- Base class reduces code duplication across generators
- Validation happens at both compile-time and runtime

## Next Steps
- Phase 2: Update frontend with provider-specific config builders
- Phase 3: End-to-end testing with all three providers
- Add Jest unit tests for each generator
- Implement CI/CD pipeline

- 7 field types: string, number, boolean, date, json, array, reference
- Model options: timestamps, soft delete
- Add/edit/delete models and fields
- Modal-based editing experience
- Integrated as step 4 in wizard flow

### Backend Integration
- New API endpoints:
  - POST /api/bootstrap/deploy - Deploy with bootstrap request
  - POST /api/bootstrap/validate - Validate bootstrap request
- BootstrapAdapter integrated in deployment-orchestrator
- Type-safe communication frontend ↔ backend

### Developer Experience
- Automated validation script (./scripts/validate-types.sh)
- Comprehensive methodology documentation
- Working_Docs/ folder (gitignored) for internal planning
- Quick reference guides and testing checklists

## Architecture

- Clean separation: public API vs internal implementation
- Adapter pattern for transformation and validation
