perf(morecolors): low-level hashtable optimization

[Rushaway]

Performance Optimization: Low-Level Hashtable Implementation (See benchs)

Overview

Replace high-level StringMap with optimized low-level Hashtable implementation, achieving 12-50% performance improvements through direct memory control and custom hash functions.

Technical Changes

• Migrated from StringMap to direct Hashtable operations
• Implemented custom hash functions optimized for color name patterns
• Manual memory management for optimal cache locality
• Eliminated API abstraction overhead
• Early skip for Observers prints
• Cache current engine value
• Remove regex

Performance Results

• Average improvement: ~37% faster execution
• Best case: 49.66% improvement (CRemoveTags)
• Consistent gains: All functions benefit from reduced overhead

Benefits

• ✅ Direct hash table control for maximum performance
• ✅ Custom hash functions tuned for color lookup patterns
• ✅ Eliminated high-level API overhead
• ✅ Better memory utilization and cache performance
• ✅ Maintained full compatibility

✅ Summary

• Rushaway version is faster in every function compared to the original.
• Performance gains range from ~12% to ~50%, depending on the function.
