Add a command to list available LLM models

[rakotomandimby]

Describe the feature or problem you'd like to solve

Default model is Sonnet 4, GPT-5 is also usable, but a command to list them all is good.

Proposed solution

Create a /list-models command to list the available models and their factor (anthropic models are 10x, OpenAI 1x, but do mention the factors)

Example prompts or workflows

Thanks for the suggestion @rakotomandimby! This is definitely feedback we've heard from a few places and are tracking it internally (team: it's 4818).

I think this is solved by /models now:

Cheers!
