feat(tools): add progressive disclosure and enhance shell safety
Progressive tool disclosure: - tool_search: discover tools by keyword without loading all schemas - tool_call: invoke a discovered tool by name - Registry supports gateway vs hidden tool visibility modes - Full test coverage for progressive disclosure flow Shell tool enhancements: - Configurable command timeout with context cancellation - Blocked command safety list (rm -rf /, etc.) - Working directory validation - Improved output truncation for large results Subagent and toolloop updates: - Migrate subagent to accept fantasy.LanguageModel interface - Update toolloop for Fantasy SDK response format - Adapt tool execution for new message types
