The ruchy optimize command has an exceptionally sophisticated CLI interface but returns "Command not yet implemented" when executed.

Reproduction

$ ruchy --version
ruchy 3.152.0

$ ruchy optimize file.ruchy
Command not yet implemented

Expected Behavior

Based on help text, should provide:

• Hardware-aware optimization analysis (Intel/AMD/ARM profiles)
• Analysis depths: quick, standard, deep
• Cache behavior analysis
• Branch prediction analysis
• Vectorization opportunities
• Abstraction cost analysis
• Hardware benchmarking
• Multiple output formats (text, json, html)

Impact

• Cannot provide optimization guidance for performance-critical code
• Missing competitive feature (like Rust profilers)
• Cannot demonstrate hardware-aware optimization workflows

Verification

Tested on 65 Ruchy files - 100% return "Command not yet implemented"
