feat(es/transformer): Implement statement injection for static properties Implement static property initialization using statement_injector: - Add pending_class_stmt_stack to track statement addresses - Implement enter_stmt hook to capture class declaration addresses - Complete emit_static_initializers to generate: * Static property assignments (C.prop = value) * Private static property WeakMap.set calls * Private static accessor WeakMap.set calls * Private method function declarations The implementation uses enter_stmt to store the statement pointer, then injects statements after the class declaration via statement_injector. Note: Tests are still failing - static initializers are not being emitted. Further investigation needed to understand why statement_injector is not working as expected. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 (1M context) <noreply@anthropic.com>
