* refactor(loop): implement isolated subgraph execution for LoopComponent
- Refactor LoopComponent to execute loop body as isolated subgraph
- Add create_subgraph method to Graph class for creating isolated subgraphs
- Add loop_utils with get_loop_body_vertices helper function
- Add on_end_vertex event emission in async_start for progress tracking
- Add comprehensive tests for subgraph execution and event emission
This change enables proper vertex event streaming during loop execution
by running each iteration as an isolated subgraph with its own context.

* [autofix.ci] apply automated fixes (attempt 2/3)
* [autofix.ci] apply automated fixes (attempt 3/3)
* fix: Improve subgraph event streaming to UI
- Add event types to stream token event manager (end_vertex, error, build_start, build_end)
- Preserve start_component_id in async_start for proper subgraph execution
- Fix has_chat_output/has_chat_input to use vertex.base_name instead of string matching
- Add _stream_to_playground check to allow inner graph components to send events
- Fix _send_message_event to properly extract and forward message IDs

* fix: Add warning log for missing custom_component in loop item injection
* refactor: Simplify loop event tests while preserving critical coverage
Reduced test complexity by removing excessive mocking while maintaining completeå event manager propagation coverage. Event manager tests are critical for ensuring UI updates work correctly during loop execution.
* fix: Update Google dependency version to 2.5.0 across multiple components
* fix: Update value format in Research Translation Loop JSON for clarity
* fix: Inject loop items into HandleInput fields via raw_params
HandleInput fields (type="other") were receiving None instead of loop items
because:
1. Fields with type="other" are skipped during field param processing
2. Loop->Parser edge is filtered out in subgraph creation
3. updated_raw_params flag was reset too early by multiple build_params() calls
Fix:
- Inject loop items into template before prepare()
- Inject into raw_params after prepare() using update_raw_params()
- Persist updated_raw_params flag across all build_params() calls
- Reset flag in _build_each_vertex_in_params_dict() after processing
Tests:
- Add integration test exercising execute_loop_body() code path
- Verify update_raw_params() called with correct data per iteration
- Add full Loop+Parser integration test
- Fix fieldName -> field_name in existing tests

* Update Google and Vertex AI docs, starter projects, and Blog Writer component
Expanded documentation for Google Generative AI and Vertex AI components to include Gemini 1.5, 2.0, 2.5, and 3.0 series models. Updated several starter project JSONs to improve model config logic. Refactored the Blog Writer's URLComponent to remove the 'markitdown' dependency and Markdown output option, now supporting only 'Text' and 'HTML' formats. Adjusted dependency metadata accordingly.

* fix: Add IBM WatsonX URL and Project ID fields to Agent component
The Agent component was missing the IBM WatsonX-specific configuration
fields (watsonx API Endpoint and Project ID) that are required for
WatsonX models. This caused validation errors when using WatsonX models
with the Agent.
Changes:
- Add DropdownInput for watsonx API Endpoint (base_url_ibm_watsonx)
- Add StrInput for watsonx Project ID (project_id)
- Pass watsonx_url and watsonx_project_id to get_llm() call
- Add dynamic show/hide logic in update_build_config() for WatsonX fields

Add validation for complex mustache patterns (sections, conditionals,
partials, etc.) in the validate_prompt function when using mustache mode.
Previously, syntactically valid but unsupported patterns like
{{#section}}{{/section}} were accepted during save but caused runtime
errors with "Complex mustache syntax is not allowed".
Now the same validation that runs at runtime also runs during the
Check & Save phase, providing immediate feedback to users.

* Add global variable mode to TextInputComponent
Introduces a 'Use Global Variable' boolean input to the TextInputComponent, allowing users to toggle between multiline text input and a single-line, password-masked input for selecting global variables. Updates the MultilineInput class to support a 'password' attribute, and adjusts the component index to reflect these changes.
* Add 'Use Global Variable' option to TextInputComponent
Introduces a 'use_global_variable' boolean input to the TextInputComponent in all starter project JSONs. This option allows users to select from global variables, disabling multiline editing and enabling password masking when active. The update includes logic in the component code to dynamically adjust the input field configuration based on this setting.
