v4.5.0: Hybrid Observation & Semantic Memory

Major Architectural Upgrades

• Hybrid Observation: The Brain now observes the world directly using read-only tools like ls, grep, and read_file, skipping worker turns for simple information gathering.
• Semantic RAG Memory: Memory retrieval is now dynamic. Instead of loading the full history, NightShift finds the top 3 most relevant 'Lessons Learned' for each task.
• Speed & Efficiency: Reduced mission turns by up to 40% and drastically cut context window noise.
