Redesign: Left sidebar with categorized filters, search input, and checkbox-style selections #39
Description
Current State
The left sidebar currently shows an alphabetized list of all providers. This doesn't scale well and makes it hard to find specific providers.
Proposed Redesign
- Categorized filters: Group providers (Cloud Providers, Frontier Models, etc.)
- Search input: Allow filtering providers by name
- Checkbox-style selections: Make it clearer which providers are selected
