feat(constructor): implement birth() syntax and pack transparency system

## 🌟 birth() Constructor Implementation
- Add BIRTH token to tokenizer (src/tokenizer.rs:37,403)
- Implement birth() parser support (src/parser/mod.rs)
- Add birth() interpreter support with priority system
- Priority: birth > pack > init > Box名

## 🚨 Fix Documentation Inconsistencies
- Fix delegation-system.md: pack → birth unified
- Fix box-design/README.md: add pack-specific section
- Fix LANGUAGE_GUIDE.md: birth unified, pack builtin-only
- Fix CLAUDE.md: birth philosophy, pack system separation

## 📋 pack Transparency System Design
- Create phase_8_8_pack_transparency_system.md specification
- Establish correct pack definition: builtin Box inheritance only
- Design user-transparent system: from BuiltinBox() → internal pack
- Comprehensive test cases and implementation requirements

## 🧪 Testing
- Add test_birth_simple.nyash: birth() functionality verification
- Document constructor name decision process
- Prepare for Copilot implementation with clear specifications
