fix: change default model to ollama/llama3 and trim config to 5 models

Fixes #563: default model changed from glm-4.7 (Zhipu AI) to llama3
(local Ollama — free, no API key needed).

Fixes #567: model list trimmed from 18 to 5 essential entries (ollama,
openrouter, anthropic, openai, deepseek). Removed 13 niche providers
to reduce config from ~265 lines to ~80.
