- Create model catalog (src/shared/domain/models.ts) with 12 models
from OpenAI, Anthropic, and Google including tier metadata
- Replace free-text model input with custom ModelSelect dropdown
grouped by provider with colored provider icons (green AI for
OpenAI, orange A for Anthropic, blue G for Google)
- Show tier badges (premium/standard/fast) on each model option
- Highlight currently selected model with indigo accent
- Update ActivityPanel to show provider icons on model badges
for visual consistency across the app
