VERSION: 0.2.0
SUMMARY:
  - AOS runtime moved to AOS_HOME (default ~/.architectos)
  - aos-chat updated to use AOS_HOME for chats and command logs
  - aos_rag.py updated to store SQLite DB under AOS_HOME/data
  - Introduced generic cleanup menu (tools/aos_cleanup.py)
  - Improved RAG embedding with automatic context-size fallback
  - Project root and AOS runtime are now cleanly separated
  - Stable 3-tool architecture: RUN, WRITE, READ
  - Safety model leans on OS ACLs instead of custom tool restrictions

KEY PATHS:
  - Runtime: ~/.architectos
  - Logs: ~/.architectos/logs/commands
  - Chats: ~/.architectos/chats
  - RAG DB: ~/.architectos/data/aos_rag.db

BREAKING CHANGES:
  - Old logs/chats written under a project root (e.g. ~/ArchitectOS) are no longer used
  - Tools or scripts expecting logs in the project root must update paths to use AOS_HOME
