The OpenRouter provider only listed 2 free models, so users with
paid accounts couldn't access their models through the CLI (#337).
Added popular paid models (Claude Sonnet 4, Gemini 2.5, GPT-5) to
both the quick-thinking and deep-thinking model lists. Also added
an 'Enter custom model ID' option that prompts for any OpenRouter
model ID, so users aren't limited to the hardcoded list.
