Add register_external_learning_proposal: bridge external learning to evolution

Fix auto_evolve: use correct feedback_loop API

Add db_common.py and memory_db.py dependencies

Add Critic Engine: review external learning proposals for redundancy and resource fit

Add Critic safety check: protect core files and block dangerous operations

Add MiroThinker-inspired interactive evolution: multi-round feedback loop

Add Docker sandbox support to evolution_executor

Add External Learning integration section

Add README: describe self-evolution core modules

Self-Evolution: Goal-driven autonomous evolution engine (8 modules)
