feat: Model tool use capability should be auto-detected

[louis-menlo]

Users now have to edit model to enable tools which is really bad UX. Tool capability should be auto-detected via GGUF chat template.

Current issue:

• Users must manually edit models to enable tool use
• Poor user experience requiring manual configuration
• Tool capability is not automatically recognized

Proposed solution:

• Auto-detect tool use capability via GGUF chat template
• Eliminate manual tool configuration steps
• Improve overall user experience

Edge cases to cover:

• Users with existing cortex models in their app data folder
• Import model functionality should also have tool capability auto-detected
• The initial idea using model catalog doesn't cover these edge cases

Implementation considerations:

• Parse GGUF chat templates to determine tool support
• Handle existing models in user directories
• Ensure imported models are properly detected
• Provide fallback mechanisms for edge cases
