#239, #240, #241, #242, #243, #244, #245) Introduce structured tool definitions via ToolRegistry with 7 built-in tools, sandboxed FileExecutor for file operations, and CompositeExecutor routing by tool_id. Raise iteration cap from 3 to configurable 10 with doom-loop detection (3 consecutive identical outputs) and context budget check at 80% threshold.
