feat: implement project-level Prettier with automated formatting

- Add comprehensive Prettier configuration with .prettierrc and .prettierignore
- Integrate Prettier with ESLint using eslint-config-prettier and eslint-plugin-prettier
- Set up automated formatting with Husky pre-commit hooks and lint-staged
- Add CI/CD checks for code formatting in GitHub Actions workflow
- Create development setup script for consistent environment configuration
- Configure VS Code settings for automatic format-on-save
- Add EditorConfig for cross-editor formatting consistency
- Format entire codebase (200+ files) with consistent style rules
- Add npm scripts: format, format:check, format:fix, setup:dev, ci:check
- Update documentation with formatting guidelines and commands

Code formatting now runs automatically across all environments:
• On save in supported editors (VS Code, etc.)
• Pre-commit via git hooks (lint-staged + husky)
• CI/CD pipeline validation
• Manual formatting via npm scripts

Ensures consistent code style regardless of developer environment or editor.

+### Code Quality Tools
+
+This project uses automated code quality tools that run across all environments:
+
+- **Prettier** - Code formatting (runs on save, pre-commit, and CI)
+- **ESLint** - Code linting with TypeScript support
+- **lint-staged** - Run tools only on staged files (pre-commit hook)
+- **Husky** - Git hooks for automated quality checks
+- **EditorConfig** - Consistent editor settings across environments
+
+### Automatic Formatting
+
+Code formatting happens automatically in multiple places:
+
+- **On Save**: Prettier formats files when you save in your editor
+- **Pre-commit**: lint-staged runs formatting on staged files before commits
+- **CI/CD**: GitHub Actions checks formatting on every pull request
+- **Manual**: Run `pnpm format` or `pnpm format:fix` anytime
+
 ### Build Performance
 
 - **Development Build**: ~2.5min (30% improvement)
