Simplify AutoCloseable refactor by extracting common patterns
- FromTag/ImportTag: Deprecated methods now call wrapper methods with automatic cleanup - AstMacroFunction: Deprecated method calls wrapper but preserves manual cleanup contract - Context: Extract common pushToStackWithWrapper() pattern to reduce duplication - Eliminates code duplication while maintaining backwards compatibility - All tests pass, no behavioral changes 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
