- Split pruning_and_callbacks into pruning and early_stopping
- Split advanced_features into async_parallel, journal_storage, ask_and_tell, multi_objective
- Each example now requires only its own feature flag
- Trim sampler_comparison winner logic and verbose header
- Update CI workflow and README to match new example names
The old example used the removed string-based trial.suggest_float()
API. Updated to use FloatParam::new() with param.suggest(trial).
