Code Review

This pull request introduces support for the ollama_cloud backend for wiki reviews. Key changes include updating the OllamaReviewer to support bearer authentication and a 120-second timeout, as well as integrating the new backend into the configuration resolution logic. Review feedback identifies a potential crash if ollama_cloud is used as the default backend because build_wiki_backend was not updated. Additionally, it is suggested to prioritize specific backend configurations for API keys and URLs over global settings to allow for more granular control.

[gemini-code-assist]

Adding ollama_cloud to this list allows it to be automatically picked up as the review backend if it is set as the default_backend in the configuration. However, build_wiki_backend (lines 615-664) has not been updated to support ollama_cloud.

If a user sets default_backend = "ollama_cloud" in their config.toml, the application will crash with an "Unknown backend" error during the wiki generation phase (line 220) before it even reaches the review phase. Please ensure build_wiki_backend is also updated to handle ollama_cloud or reconsider adding it to this matches! block.

[gemini-code-assist]

The API key and URL lookup for ollama_cloud should ideally check the specific wiki backend configuration first, consistent with how the ollama (local) backend is handled. This allows users to provide specific credentials or endpoints for wiki reviews that differ from the global graph or log settings.
