✨ Major code quality improvements: • Fixed all unused variable and parameter warnings • Added appropriate #[allow(dead_code)] annotations • Renamed constants to follow Rust naming conventions • Achieved completely warning-free codebase 🔧 Key changes: • Parser expressions: Fixed arg_count and statement_count usage • MIR modules: Added dead_code allows for future-use code • Backend modules: Prefixed unused parameters with underscore • Effect constants: Renamed 'read' to 'READ_ALIAS' for conventions 📊 Results: • Before: 106 warnings (noisy build output) • After: 0 warnings (clean build) • Improvement: 100% warning reduction 🎯 This continues the bug fixing initiative "つづきのしゅうせいおねがいにゃ！" from Phase 9.75i (birth() fixes, static methods, Copilot apps). 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
