Summary of Changes

Hello @gemini-cli-robot, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request represents an automated attempt to backport a critical fix related to the Codebase Investigator's thinking budget to a preview release branch. While the intent is to prevent runaway processes by capping the thinking budget, the automated cherry-pick encountered merge conflicts. Manual intervention is now required to resolve these conflicts and ensure the successful integration of the change, which also includes updated documentation and a new JSON schema for settings.

Highlights

• Automated Cherry-Pick with Conflicts: This PR is an automated cherry-pick of commit 59e0b10 to the release/v0.12.0-preview.9-pr-12416 branch, but it has resulted in merge conflicts that require manual resolution.
• Codebase Investigator Thinking Budget: The underlying change from the cherry-picked commit caps the 'thinking budget' for the Codebase Investigator agent to 8192 tokens, preventing potential runaway thought loops.
• Updated Configuration Documentation: New experimental settings for the Codebase Investigator (max turns, max time, thinking budget, model) and general hook configurations have been added to the docs/get-started/configuration.md file.
• New Settings JSON Schema: A new schemas/settings.schema.json file has been introduced to provide a structured JSON schema for Gemini CLI settings, enabling better IDE completion and validation.
