…gic to dedicated `recommender` module

- Removed the inlined `VisualizationRecommender` class from `suggestions.py` and imported it from `visual_suggestion.recommender`
- Simplified `suggestions.py` to serve as a lightweight interface for visualization recommendation
- Updated `__init__.py` imports to correctly expose `VisualizationRecommender` from its new package
- Enhanced `recommender()` function to support:
  - `StrategyName` parameter for configurable model selection strategy
  - `selected_models`, `interactive`, and `timeout` arguments for flexible runtime behavior
- Improved module clarity and reduced redundancy by centralizing model, API, and ensemble logic under the recommender system

…recommender` modules with consistent `API` handling and helper usage

- Added default argument values to `VisualizationRecommender` and `PlotExplainer` constructors for strategy, models, timeout, and interactivity
- Introduced `self.api_keys` and standardized `ProviderManager` initialization across both components
- Updated `test_explanations` to use shared helper functions `encode_image` and `save_plot_to_image` from `core.utils`
- Revised `test_plotgen` to align with new `_default_plots` naming and initialization logic
- Refactored `test_suggestions` to leverage new `ResponseParser`, updated recommendation pipeline, and aligned prompt/query flow
- Commented deprecated internal tests tied to removed private methods (`_get_all_recommendations`, `_parse_recommendations`, etc.)
- Ensured test assertions verify model availability and provider correctness under new recommender structure
