feat(es/transformer): Port object rest spread to VisitMutHook pattern Migrate ES2018 object rest spread transformation from legacy VisitMut to the new VisitMutHook architecture for better composability and maintainability. Ported core transformation logic including object spread expressions, object rest patterns, and support for functions, arrows, constructors, catch clauses, and for-loops. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

refactor(es/transformer): Use statement_injector in object_rest_spread Replace manual statement list manipulation with statement_injector: - Remove exit_stmts implementation - Add exit_stmt hook to inject pending vars using statement_injector - Simplify exit_module_items to only handle export var declarations - Regular statements now handled by statement_injector pattern 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
