feat(core): add setting to disable loop detection

[SandyTao520]

TLDR

This PR adds a new setting model.disableLoopDetection to allow users to disable the automatic detection and prevention of infinite loops. This is useful for scenarios where productive repetitive behavior is incorrectly flagged as a loop.

Dive Deeper

The LoopDetectionService currently monitors both tool call repetitions and content streaming patterns. While effective, it can sometimes produce false positives. By adding this setting, users can opt-out of this behavior globally via their settings.json or the /settings command.

Changes include:

• Core configuration updates to support the new flag.
• Integration into the CLI settings schema and JSON schema for IDE support.
• Documentation updates in configuration.md and settings.md.
• Marking the setting as requiring a restart.

Reviewer Test Plan

1. Open Gemini CLI.
2. Run /settings and navigate to the Model section.
3. Verify "Disable Loop Detection" is present and defaults to false.
4. Enable it and verify it's saved to settings.json.
5. Verify that with the setting enabled, LoopDetectionService bypasses its checks.

Summary of Changes

Hello @SandyTao520, 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 introduces a new configuration option to control the automatic loop detection mechanism within the system. This enhancement provides users with the flexibility to bypass the loop detection service, particularly in cases where the current system might misinterpret intended repetitive actions as infinite loops, thereby improving the user experience for specific workflows.

Highlights

• New Configuration Setting: A new setting, model.disableLoopDetection, has been introduced to allow users to disable the automatic detection and prevention of infinite loops.
• Purpose: This setting addresses scenarios where productive repetitive behavior might be incorrectly flagged as a loop by the LoopDetectionService, providing greater flexibility.
• Integration and Documentation: The new setting is integrated into the CLI settings schema, JSON schema for IDE support, and documented in configuration.md and settings.md.
• Restart Requirement: The model.disableLoopDetection setting requires a restart to take effect.

Code Review

This pull request introduces a new setting, model.disableLoopDetection, to give users the ability to turn off the automatic loop detection mechanism. The changes are well-implemented across the configuration, core logic, and documentation. The new setting is disabled by default for safety, and the implementation in LoopDetectionService is straightforward and correct. The inclusion of unit tests to verify the new behavior is also appreciated. Overall, this is a solid contribution that adds a useful feature for advanced users who might encounter false positives with the loop detection system.
