Reverse engineering tools per mode; raw firmware in decompile; skill

- AgentConfig.reverse_tools (Settings -> Agents & commands) gives any mode
  binary_info and decompile; the clean-room check of the tools applies to
  craft only (ToolCtx.clean_room = clean room && craft).
- decompile: optional processor (Ghidra language id) and base_address for raw
  images (BinaryLoader); separate cache per processor/address.
- Skill "reverse-engineering": identify, convert HEX, processor table for
  common chips, decompile, explore, notes in analysis/.
