- Add version-trimmed alias generation to handle trailing version zeros (e.g. '4.0' -> '4')
- Track newly added base model names in 'new_models_added_list' field
- Include Ideogram 4.0, Boogu, and PolyGen in base-models registry
- Update web resolver to match aliases using both original and version-trimmed tokens
- Enhance base models update UI to show which new models were added
Uses an exact alias membership check instead of substring matching to prevent
false positives, e.g. 'zimage' alias no longer incorrectly matches
'zimagebase'.
