perf(codegen): reorder match arms based on usage patterns Reorder Statement and Expression match arms to align with parser frequency, improving branch prediction performance. Changes: - Statement: BlockStatement, ExpressionStatement, VariableDeclaration and control flow statements moved to top, TS-specific moved to bottom - Expression: Identifier, member access, calls, and literals moved to top, JSX and TS assertions moved to bottom The new order follows the parser's pattern matching sequence, which reflects real-world JavaScript/TypeScript code frequency. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
