Add Biome.js Configuration

This PR introduces Biome.js as a new development tool for improved code formatting and linting. Key changes include:

• Add biome.json configuration file with customized formatting and linting rules
• Update .editorconfig to use 2-space indentation while maintaining tab style
• Install @biomejs/biome v1.9.4 as a dev dependency

The Biome configuration includes:

• JavaScript/TypeScript-specific formatting rules (single quotes, trailing commas, etc.)
• Comprehensive linting rules for complexity, correctness, style, and suspicious patterns
• Separate rule overrides for TypeScript files
• Carefully curated ignore patterns for specific files and directories

This change will help maintain consistent code style across the project while catching potential issues early in development.

PR Plan
