Fix issue #6277 where TextMessage was used but not imported in three code cells
of the custom agents documentation, causing NameError when users run the examples.

Changes:
- Add TextMessage to imports in ArithmeticAgent section
- Add TextMessage to imports in GeminiAssistantAgent section
- Add TextMessage to imports in Declarative GeminiAssistantAgent section

The CountDownAgent section already had the correct import.

Fixes #6277

- Fix missing tools parameter in reflection flow (Issue #6328)
- Add tool_call_loop parameter for repeated tool calls (Issue #6268)
- Maintain backward compatibility (both features disabled by default)
- Add comprehensive tests and documentation

Resolves: #6328, #6268

This reverts commit d07898b.

Resolved conflicts by:
- Merging tool call loop implementation with streaming tool execution
- Adding message ID support to tool call loops
- Updating imports to include StaticStreamWorkbench and ToolResult
- Combining streaming tool execution with existing loop logic
- Fixed test conflicts by removing orphaned code

The merged implementation preserves both the tool call loop functionality
and the streaming capabilities from main branch.
