Code Review

This pull request updates the troubleshooting documentation in docs/resources/troubleshooting.md to add a section addressing an issue where the Gemini CLI hangs on 'Initializing...' on Linux. It details the symptoms, cause (missing ripgrep binary falling back to a network path with a long timeout), fix, and references the related issue #20433. There are no review comments, and I have no feedback to provide.
